Export BGP Table to ibgp session

Hey,

I have following setup:

SRV1 -> SRV2 -> SRV3

SRV1:
eBGP session to external transit provider
iBGP session to SRV2

SRV2:
iBGP session to SRV1 & SRV3

SRV3:
iBGP session to SRV2

I announce a /24 Subnet at SRV3 and wont to export it through SRV2 & SRV1 to my Transit Provider.
Also, I want to export the full table from my Transit provider through SRV1 & SRV2 to SRV3.

But…it looks like something is blocking it after the first iBGP “hop”.
SRV2 knows my announced /24 Subnet and also the full table that I import & export from SRV1.
But, SRV1 don’t know my /24 Subnet and SRV3 don’t get the full table that I have at SRV2…

After reading some old Vyatta docs it looks like “allowas-in” and “maximum-paths ibgp” are the settings to fix that issue, but… they don’t change anything :frowning:

Anyone have a Idea how to solve this issue?

Hey,

A few questions:

First: do you use prefix filters and route maps ?
Second: how does your BGP config look like on each SRV ? - Replace ips that are public - INCLUDE PREFIX FILTER AND ROUTE MAPS IF PRESENT

Until those 2 questions are answered it will be really hard to assist you properly.
