Hi Misc@ and Claudio@,
On 17th June kernel and userland, I experienced a really slow updates on
FIB, while doing a BGP failover test.
It's a simple test, I had 2 different internet peers, both sends full
prefix. With the first scenario, when I shut the peer1 down, it still
forwards to peer1. I need a "bgpctl reload" to move the forwarding to
peer2. And, when I feel like to move the traffic (upstream) back to peer1,
it doesn't simultaneously move back, and I still need to do "bgpctl
reload" to bring it back to its normal behaviour.
The second scenario is to deny all prefixes received from peer1. By
modifying ke bgpd.conf, and then "bgpctl reload", the upstreams still
choose to peer1. I evaluate RIB table "bgpctl sh rib" and it does changed,
prefixes from peer1 is no longer existed. But on "bgpctl sh fib" the
nexthop still points to peer1. I waited for about 15 minutes, it still not
changing its FIB record. To restore the configuration, modify bgpd.conf
back to receive full prefix from both peers and reload, and some strange
behaviour exist, instead of still forwarding to peer1, the router forwards
traffic to peer2, which I was expecting before. I need to issue a second
reload to move the forwarding back to peer1.
Any insight would be appreciated,
Thanks,
