BGPD error
by Emanuel - Tianguá.com 10 Mar '20

10 Mar '20

Hello, I'm new here! I am testing or frrouting and I am facing some problems! The first one and what to follow, following the manual of the frrouting website or the BGP service not logged in to configure. Then take an example file / var / shared / doc / .... and use it as an example, just as BGPD does not load the settings! So I went to the daemons file and put the parameter "-f /etc/frr/bgpd.conf". From there or bgpd loads and manages to login via telnet! The problem and what bgpd keeps restarting over and over! Any tips or study documents? -- Sua foto ou logo Emanuel Magalhães Cunha Proprietário | Adm.

high cpu usage because of 100s of ping to ospf peers by user frr
by neeraj kharbanda 07 Mar '20

07 Mar '20

Hi, i'd got a basic setup of ospf with 5 6 ospf neighbours. Everyon now and then there is very high cpu usage. Htop shows 100s of ping to ospf peers by user frr (just 5 to 8 peers). Other peers are mikrotik. Makes the system instable till kill all the pings. Its a pppoe server with 4000+ pppoe interfaces. Kindly help in resolving the problem. -- Thanks and Regards >From Chaos to Control Neeraj Kharbanda +919911145461

Zebra FIB update/withdrawal looping issue
by Templin (US), Fred L 26 Feb '20

26 Feb '20

I have a simple BGP configuration with one "hub" ASBR and two "spoke" ASBRs. The spoke ASBRs report IPv6 BGP routes to the hub, while the hub originates "default" to the spokes. So, the hub ASBR receives all advertised routes while the spokes receive only "default". When I run my network, BGP routes indeed show up at the hub ASBR and Zebra installs them in the FIB. However, after about 2-5 seconds, Zebra withdraws the routes and then about 2-5 seconds later it reinstalls them in the FIB again. This process recurs indefinitely even though there are no dynamic BGP protocol updates coming from the spokes. Any idea what could cause Zebra on the hub ASBR to loop and repeatedly install and withdraw the BGP routes? Thanks - Fred PS I am running the latest FRR release on Ubuntu 16.0.4.

What 'ge' 'le' really means ?
by Simon Jones 20 Feb '20

20 Feb '20

Hi all, In this command: > gyw-229(config)# ip prefix-list test_ipv4_1_1 seq 10 permit 192.18.8.0/24 > ge 24 > % Invalid prefix range for 192.18.8.0/24, make sure: len < ge-value <= > le-value > gyw-229(config)# ip prefix-list test_ipv4_1_1 seq 10 permit 192.18.8.0/24 > ge 25 we see 'ge' means greater. But in doc: > ge command specifies prefix length. The prefix list will be applied if the > prefix length is greater than or equal to the ge prefix length So what's 'ge' really means? And how to set equal command? Set equal command using 'ge xxx le xxx' before, but if 'ge' means greater, how to set? Use this command? > ip prefix-list test_ipv4_1_1 seq 10 permit 192.18.8.0/32 ---- Simon Jones

Fwd: trying to find example babeld.conf for use with FRR and Wireguard
by brian mullan 16 Feb '20

16 Feb '20

I have FRR and BGP working well with WireGuard but I'd really like to try Babled. However, I've searched the internet for a couple days now and the only babeld.conf files I've found are for openwrt use. Can anyone point me to an example babeld.conf for FRR that might work with WireGuard? thanks for any information or links. Brian

Changing BGP route map mid-session causes zebra to spin out of control
by Rudy Rucker 12 Feb '20

12 Feb '20

TL;DR: Having a '0.0.0.0/0 le 29' in a BGP prefix-list on a BGP session that has a full table can freak out zebra. If I go in and change a route-map, the box load goes to 100+ and starts dropping packets. The route-map had this prefix-list line ip prefix-list DEFAULT-IN-ip4 seq 99 permit 0.0.0.0/0 le 29 that seemed to break things, but changing it to: ip prefix-list DEFAULT-IN-ip4 seq 99 permit 0.0.0.0/0 le 24 fixes it. Repeatable: launch FRR with route-map COGENT-IN deny 10 match ip address prefix-list AS32329-ip4 route-map COGENT-IN permit 20 match ip address prefix-list COGENT-TEST-ONE-BLOCK set local-preference 100 set weight 101 Wait a few minutes, then change to route-map like this: orange(config)# route-map COGENT-IN permit 20 orange(config-route-map)# match ip address prefix-list DEFAULT-IN-ip4 orange(config-route-map)# set local-preference 100 orange(config-route-map)# set weight 101 And then load goes over 100 Here are the lists.... ip prefix-list COGENT-TEST-ONE-BLOCK seq 10 permit 38.0.0.0/8 le 24 ip prefix-list COGENT-TEST-ONE-BLOCK seq 20 deny any ip prefix-list DEFAULT-IN-ip4 seq 11 deny 10.0.0.0/8 le 32 ip prefix-list DEFAULT-IN-ip4 seq 12 deny 172.16.0.0/12 le 32 ip prefix-list DEFAULT-IN-ip4 seq 13 deny 192.168.0.0/16 le 32 ip prefix-list DEFAULT-IN-ip4 seq 14 deny 169.254.0.0/16 le 32 ip prefix-list DEFAULT-IN-ip4 seq 15 deny 127.0.0.0/8 le 32 ip prefix-list DEFAULT-IN-ip4 seq 99 permit 0.0.0.0/0 le 29 Output of truss on 'zebra' (I don't claim to really understand this output, other than reading 'Resource temporarily unavailable'. # truss -p 919 seteuid(0xa8) = 0 (0x0) read(6,"\M-H\0\^E\^B\^F\0\0\0B\M^@\0\0\a"...,1192) = 200 (0xc8) seteuid(0x0) = 0 (0x0) write(4,"\^A",1) = 1 (0x1) getrusage(RUSAGE_THREAD,{ u=27.163188,s=34.122484,in=5,out=7 }) = 0 (0x0) write(7,"\M-H\0\^E\^B\^F\0\0\0\^A\M^@\0\0"...,200) = 200 (0xc8) poll({ 6/POLLIN 12/POLLIN 15/POLLIN 16/POLLIN 3/POLLIN },5,0) = 2 (0x2) read(3,"\^A",64) = 1 (0x1) read(3,0x7fffffffe9b0,64) ERR#35 'Resource temporarily unavailable' write(7,"\M-H\0\^E\^A\^D\0\0\0\^C\M^@\0\0"...,200) = 200 (0xc8) seteuid(0xa8) = 0 (0x0) seteuid(0x0) = 0 (0x0) write(7,"\M-H\0\^E\^B\^F\0\0\0\^A\M^@\0\0"...,200) = 200 (0xc8) getrusage(RUSAGE_THREAD,{ u=27.163263,s=34.122484,in=5,out=7 }) = 0 (0x0) write(4,"\^A",1) = 1 (0x1) getrusage(RUSAGE_THREAD,{ u=27.163279,s=34.122484,in=5,out=7 }) = 0 (0x0) write(7,"\M-H\0\^E\^A\^D\0\0\0\^C\M^@\0\0"...,200) = 200 (0xc8) getrusage(RUSAGE_THREAD,{ u=27.163294,s=34.122484,in=5,out=7 }) = 0 (0x0) seteuid(0xa8) = 0 (0x0) read(6,"\M-H\0\^E\^A\^D\0\0\0C\M^@\0\0\a"...,1192) = 200 (0xc8) write(4,"\^A",1) = 1 (0x1) getrusage(RUSAGE_THREAD,{ u=27.163335,s=34.122484,in=5,out=7 }) = 0 (0x0) seteuid(0x0) = 0 (0x0) poll({ 6/POLLIN 12/POLLIN 15/POLLIN 16/POLLIN 3/POLLIN },5,0) = 2 (0x2) read(3,"\^A\^A",64) = 2 (0x2) read(3,0x7fffffffe9b0,64) ERR#35 'Resource temporarily unavailable' write(7,"\M-H\0\^E\^B\^F\0\0\0\^A\M^@\0\0"...,200) = 200 (0xc8) getrusage(RUSAGE_THREAD,{ u=27.163391,s=34.122484,in=5,out=7 }) = 0 (0x0) write(4,"\^A",1) = 1 (0x1) getrusage(RUSAGE_THREAD,{ u=27.163421,s=34.122484,in=5,out=7 }) = 0 (0x0) write(7,"\M-H\0\^E\^A\^D\0\0\0\^C\M^@\0\0"...,200) = 200 (0xc8) getrusage(RUSAGE_THREAD,{ u=27.163444,s=34.122484,in=5,out=7 }) = 0 (0x0) read(6,"\M-H\0\^E\^B\^F\0\0\0B\M^@\0\0\a"...,1192) = 200 (0xc8) seteuid(0xa8) = 0 (0x0) write(4,"\^A",1) = 1 (0x1) seteuid(0x0) = 0 (0x0) getrusage(RUSAGE_THREAD,{ u=27.163492,s=34.122484,in=5,out=7 }) = 0 (0x0) poll({ 6/POLLIN 12/POLLIN 15/POLLIN 16/POLLIN 3/POLLIN },5,0) = 2 (0x2) read(3,"\^A\^A",64) = 2 (0x2) write(7,"\M-H\0\^E\^B\^F\0\0\0\^A\M^@\0\0"...,200) = 200 (0xc8) read(3,0x7fffffffe9b0,64) ERR#35 'Resource temporarily unavailable' write(7,"\M-H\0\^E\^A\^D\0\0\0\^C\M^@\0\0"...,200) = 200 (0xc8) I'm not positive I figured this out... maybe it is late at night and traffic levels are down.

Installing FRR on Ubuntu 18.04
by ian.2.oakley＠bt.com 10 Feb '20

10 Feb '20

Hi all, I've been trying to reinstall FRR on my Ubuntu 18.04 virtual machine, following the instructions given in the official guidance (http://docs.frrouting.org/projects/dev-guide/en/latest/building-frr-for-ubu…) but when I do I get the following error on the sudo make install stage: configure: error: libyang needs to be compiled with ENABLE_LYD_PRIV=ON. Instructions for this are included in the build documentation for your platform at http://docs.frrouting.org/projects/dev-guide/en/latest/building.html Having installed libyang from source with ENABLE_LYD_PRIV=ON, I'm not sure what's occurring. Does libyang need to be installed into the FRR directory for it to work properly?
