Fwd: Segment Routing with FRR
by 唐志军 23 Jul '18

23 Jul '18

Hello, My name is Zhijun. I am learning segment routing by using FRRouting. First, thank you for writing such a guide to setup segment routing in FRRouting. I have read this guide and set up an sr environment with 5 FRR routers. However, I cannot make it sure whether I did correctly. Bellow is my topo. [image: image.png] and this is my r1 config, [image: image.png] and I got bellow sr info, [image: image.png] I would be very grateful if you can tell me if this is right to config such an sr environment. And, in depth, how can I config a label switch path for traffic between H1 and H2, such as icmp packets? Best Reguards, Zhijun

[EVPN] ./configure options to create crash dump and debugging for EVPN

Hi, Could anyone please share the ./configure options to enable debugging information as well as crash dump ? I have BGPd crashing in an EVPN environment with this as backtrace: Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(zlog_backtrace_sigsafe+0x32) [0x7f592688fb94] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(zlog_signal+0x219) [0x7f59268900b1] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(+0x4a729) [0x7f59268a0729] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd() [0x4a12e4] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd() [0x4a15ad] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd() [0x4a1660] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd(bgp_evpn_local_vni_add+0x133) [0x4a5163] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd() [0x446f2c] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(+0x5b572) [0x7f59268b1572] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(thread_call+0x46) [0x7f59268aa5d1] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/libfrr.so.0(frr_run+0x1ae) [0x7f592688eb93] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd(main+0x1f8) [0x41cf74] Jul 13 20:08:10 li1276-116 bgpd[14597]: /usr/lib/frr/bgpd() [0x41e826] Jul 13 20:08:10 li1276-116 watchfrr[14612]: bgpd state -> down : read returned EOF This is happening randomly and is hard to reproduce so I believe a crash dump can help see where the problem is.

Fwd: Help: how to enable RPKI in FRR 5?

My bad, I forgot to send the response to the list. Also I've seen that in my first mail I misplaced the RPM link.

To: Martin Winter <mwinter(a)opensourcerouting.org> Hi Martin, thanks for your reply. I do have the RTRlib already, just as you have mentioned here and as is stated at the docs. Also, I've installed the FRR wtih RPKI package; and also I've tried by making the RPM package "manually", including the option "--enable-rpki" (the code that I've downloaded is from the branch master). Just to add more information of the problem, actually (and this is odd) the rpki commands do appear at the vtysh console as available commands: vtysh# find rpki (enable) rpki start (enable) rpki stop (enable) show rpki cache-connection (enable) show rpki cache-server (enable) show rpki prefix-table (config) rpki (config) debug rpki .... But they don't appear at the bgp daemon console whenever I connect via "telnet localhost 2605" and run the same command bgp# find rpki So, what else do you think that might be the problem? I really appreciate your help.

Help: how to enable RPKI in FRR 5?

Hi there, I've been trying to configure FRR 5.0.1 (downloaded from Github releases https://github.com/FRRouting/frr/releases/download/frr-5.0.1/frr-5.0.1-2018…) and also 5.1 (manually built as RPM from master branch) to use RPKI. Both cases in CentOS 7; there's no problem compiling nor executing the service with the zebra and bgpd daemons active. But when I try to use the rpki configuration (http://docs.frrouting.org/en/latest/bgp.html#enabling-rpki) this is not recognized by the application. For example, if I place the conf at the bgpd.conf file like the example ( http://docs.frrouting.org/en/latest/bgp.html#rpki-configuration-example) nothing happens since the configuration seems to be unrecognized. After that, I've tried to configure the rpki from the terminal (using "vtysh" or by "telnet"), like this (multiple forms, probably a little desperate): bgp# rpki % [BGP] Unknown command: rpki bgp# conf term bgp(config)# rpki % [BGP] Unknown command: rpki bgp(config)# router bgp 1 bgp(config-router)# rpki % [BGP] Unknown command: rpki I don't know if I'm missing something or what to do, could somebody here help me with this please?

6PE functionality support in FRR
by Thiruvazhiyan Lakshmanan 16 Jul '18

16 Jul '18

Hi, We are looking for using FRR in our VM for BGP 3107 functionality with 6PE support. Basically FRR should peer with peering router with ipv6-label-unicast family and advertise its v6 loopback address with the label value of 2 (Explicit null label) and the next-hop of the route to be set to its v4 loopback address. Does FRR support this currently?

BGP state shows NoNeg for IPv4 LU neighbor
by Thiruvazhiyan Lakshmanan 13 Jul '18

13 Jul '18

Hi, I am trying to use FRR in my VM for BGP 3107 functionality. While configuring the BGP neighbor with address family "ipv4 labeled-unicast", the neighbor state shows NoNeg. But the peer side router shows established. I also noticed the routes are learnt in FRR from peer router and installed in the route table. But, I am trying to advertise my VM loopback to the LU neighbor, which is not happening. Can someone help me on this?

Originating Default EVPN Type-5 Routes with frr
by Martin Mailand 12 Jul '18

12 Jul '18

Hello, I am playing around with FRR and EVPN. My setup is very simple, I have two virtual machines running Linux, which are connected back to back and are called border leaf and normal leaf. I have compiled FRR from git head with the option --enable-cumulus. Type 2,3,5 routes are working in a symmetric routing environment. Now I want to inject a default route from the border leaf, which should be a type 5 route and it should be written down to the vrf of the normal leaf. But the documentation is a bit sparse, according to the cumulus docs it should go into the vrf part of the bgp configuration: —snip— switch(config)# router bgp 650030 vrf vrf1 switch(config-router)# address-family l2vpn evpn switch(config-router-af)# default-originate ipv4 switch(config-router-af)# default-originate ipv6 switch(config-router-af)# exit switch(config-router)# exit switch(config)# exit switch# write memory —snap— source: https://docs.cumulusnetworks.com/display/DOCS/Ethernet+Virtual+Private+Netw… But with this configuration I do not see any default type 5 routes in the RIB. If I put the statements "default-originate ipv(4|6)“ into the main bgp section I get routes in the RIB. But I do not know how to read the RD (as2 0:0) And the two default routes are not in the VRF FIB either. Border leaf RIB: show bgp l2vpn evpn Route Distinguisher: as2 0:0 *> [5]:[0]:[0]:[0.0.0.0] 0.0.0.0 32768 i *> [5]:[0]:[0]:[::] 0.0.0.0 32768 i Normal leaf RIB: Route Distinguisher: as2 0:0 *>i[5]:[0]:[0]:[0.0.0.0] 192.168.0.3 100 0 i *>i[5]:[0]:[0]:[::] 192.168.0.3 100 0 i Any hint would be appreciated to get it up and running. Thanks for your time. Best regards, martin Here the two configs. border leaf: vrf vrf1 vni 8000 ! # VRF1 router bgp 1234 vrf vrf1 ! bgp router-id 192.168.10.3 ! address-family ipv4 unicast redistribute connected exit-address-family ! address-family ipv6 unicast redistribute connected exit-address-family ! address-family l2vpn evpn advertise ipv4 unicast advertise ipv6 unicast # should be here according to the cumulus docs # default-originate ipv4 # default-originate ipv6 exit-address-family ! ## Global router bgp 1234 bgp router-id 192.168.10.3 neighbor 192.168.0.4 remote-as 1234 #redistribute connected route-map loopbacks network 192.168.10.3/32 ! address-family l2vpn evpn neighbor 192.168.0.4 activate advertise-all-vni default-originate ipv4 default-originate ipv6 exit-address-family ! route-map loopbacks permit 10 match interface lo !
