Here my scenario :
Basically I have some servers which peer locally on each arista switchs.
I want one path by server on both switch. So In my example 3 paths by switchs.
1 path on sw1 (from the direct peer attached)
If I shut the peer on sw1, I got the two pathq from ibgp (thanks to additionnals paths); but it was up it was preferred.
My question is : is there an option to have both path (I think the problem is have a mix of ibgp/ebgp). ?
What routing mode do you use, Multi-agent or standard, RibD?
The statement seem normal, but if SW1 and SW2 are iBGP peers then they should exchange each other prefixes.
Note that you may want to enforce the BGP administrative distance with the BGP distance command to influence the eBGP vs iBGP selection preference away from the default : 200 for both iBGP and eBGP! ref: http://www.arista.com/en/um-eos/eos-section-31-4-bgp-commands#ww1116652
Are the subnets to the servers advertised by an IGP? If not then maybe you need to configure next-hop-self to the IBGP peers. But from your output you don’t seem to have reachability issues. I don’t see the content of your route-maps such as the one named connected-to-bgp.
I am not clear what you are trying to achieve. If you want all the prefixes to be learned by eBGP rather than a mix of iBGP+eBGP then maybe SW1 and SW2 should b eBGP peers rather than iBGP. You could correct the AS-Path.
