Quagga Slow Advertising
Hello,

In my quagga configuration, I have two peers- an IGP and an EBGP peer.

I have noticed that quagga is taking time in advertising/propagating
routes received from an ibgp peer to an ebgp peer, and also vice versa,
to the tunes of about 5-10 seconds.

Is this a normal behavior, or am I missing something in my configuration?
Quagga is being run on a sufficiently powerful machine and the ibgp peer
is localhost while ebgp peer is another virtual interface on reachable
network.

Following is the configuration:

|! router bgp 64496 bgp router-id 10.0.0.1 neighbor 127.0.0.1 remote-as
64496 neighbor 127.0.0.1 port 1790 neighbor 127.0.0.1 update-source
10.0.0.1 neighbor 127.0.0.1 route-map set-nexthop-1 out redistribute
connected neighbor 10.0.0.2 remote-as 64497 neighbor 10.0.0.2 port 179
neighbor 10.0.0.2 update-source 10.0.0.1 neighbor 10.0.0.2 route-map
set-nexthop-1 out ! route-map set-nexthop-1 permit 1 set ip next-hop
10.0.0.1 set local-preference 5 !|

Thanks in advance for any inputs on it, would be more than happy to
provide additional information.

This behavior is not Quagga-specific, but protocol specific.

See this, for example: https://supportforums.cisco.com/discussion/10835901/bgp-advertisement-interval
