received-routes.. doesn't work?

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 ().

Проблема описанна здесь: https://github.com/FRRouting/frr/issues/995, https://www.linux.org.ru/forum/admin/13617547 Проблема описанна здесь: https://github.com/FRRouting/frr/issues/995 Самое интересное, когда я создал VLAN, то OSPF каким то образом заработал. Это также касается и других протоколов, таких как eigrp. Всю делал на виртуалках. Виртуалки запущенны через libvirt.

PIM VRF
by Donald Sharp 03 Aug '17

03 Aug '17

All - The ability for PIM to work within the context of linux VRF's has been committed into master. To configure for a VRF: vrf red <---- VRF configuration, same as global configuration ip pim ecmp ip pim rp 99.1.1.1 224.0.0.0/4 interface vrf red ip pim sm The 'interface vrf red' is treated like the loopback. So if you intend to use the particular router as a RP you should configure an ip address on your vrf device and configure pim to use it. interface swp1 vrf red <----- Turn on pim on the interface as per normal ip pim sm interface swp2 vrf red ip pim sm ip igmp thanks! donald
