received-routes.. doesn't work?
by Mark Kamichoff 01 Sep '18

01 Sep '18

Hi - I'm running various 3.1-dev versions of FRR and noticed that the "show ip bgp nei <peer> received-routes" doesn't seem to work as expected on any of them. Here's an example of the relevant parts of the configuration: ! router bgp 395460 neighbor 169.254.169.254 remote-as 64515 neighbor 169.254.169.254 password <snip> neighbor 169.254.169.254 ebgp-multihop 2 address-family ipv4 unicast neighbor 169.254.169.254 soft-reconfiguration inbound neighbor 169.254.169.254 route-map DENY_ALL in neighbor 169.254.169.254 route-map DENY_ALL out exit-address-family ! route-map DENY_ALL deny 65535 ! orca# show ip bgp neighbors 169.254.169.254 routes orca# show ip bgp neighbors 169.254.169.254 received-routes BGP table version is 0, local router ID is 10.3.4.36 Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, i internal, r RIB-failure, S Stale, R Removed Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path orca# >From tcpdump and other t-shooting I know that there is an IPv4 DFZ being received, but received-routes doesn't show any of the routes that should be in the adj-rib-in. Oddly, if I remove the inbound route-map I see expected prefixes using the "routes" /and/ "received-routes" command. If I put it back, the "received-routes" shows nothing once again. It would almost seem like soft-reconfiguration isn't really enabled, but received-routes should give me an error if it wasn't and the neighbor information confirms that it is: orca# show ip bgp neighbors 169.254.169.254 <snip> For address family: IPv4 Unicast Update group 5, subgroup 5 Packet Queue length 0 Inbound soft reconfiguration allowed <----- <snip> This isn't limited to the IPv4 AF, either. I've got IPv6 peers that echibit the same behavior. Have I found a bug or am I doing something wrong? I'm happy to file a bug report. More info., if it helps: orca# show version FRRouting 3.1-dev ().

BFD with BGP
by Ashvin Lakshmikantha 22 Mar '18

22 Mar '18

Hi all, While I was able to configure bfd in frr for BGP failover, I find that the sessions are not getting established. Is this a supported feature in frr-3.0.3? Thanks, Ashvin

Hi folks, Updated documentation is now on the FRR website. User guide: https://frrouting.org/user-guide/ <https://frrouting.org/user-guide/> Developer’s guide: https://frrouting.org/dev-guide/ <https://frrouting.org/dev-guide/> This was built from the tip of master and should be accurate for the upcoming 4.0 release. Eventually I will work on a way to publish versioned documentation for each release. The developer documentation will be rolling. Thanks, Quentin

Hi, I dont know if my last query made it to the mailer. We want to adopt FRR for our saatellite hub systems. We are looking for the following protocols for our hub systems. 1)4k +BGP sessions 2)Full VRF table size of 4k+ 3)mpls l3 vpn 4)mp-bgp (vpnv4) Can somebody confirm if these protocols are currently supported by FreeRangeRouting stack?

How to configure RFC 4364 (BGP/MPLS) VPNs with FRR/bgpd
by SHAIKH, AMAN (AMAN) 01 Mar '18

01 Mar '18

Hi How do I configure FRR/bgpd to support RFC 4364 (BGP/MPLS) L3-VPNs? Specifically, I'd like to know how to configure following things: - One or more VRFs along with its import and export route targets as well as route-distinguisher. o Specifying one or more neighbors (eBGP sessions) in this VRF with IPv4(|6) address family. - One or more iBGP sessions with route-reflectors and other routers supporting VPNv4(|6) address family. thx aman
