How to configure priorites for multiple BGP Peers

Hi,

At our organisation our routers all have at least 3 BGP peers, each from a different connectivity provider.

The different providers that we use all have different internet transit CDRs.

Is there a way that I can configure a priority for the 3 BGP peers on our routers so that outbound traffic to the internet is sent to the BGP peer from the provider with the highest CDR?

Routers are C2821

How to configure priorites for multiple BGP Peers

Hi Joe,

Not sure what you mean by CDR, however as far as BGP is concerned, you have two things when it comes to BGP, one is prefixes learned via BGP ( either iBGP or eBGP) and the communities attached to those prefixes.

So, I assume you want to match particular attribute. You can do that with the help of combination of ACL or AS Path access list and Policy-maps.

How to configure priorites for multiple BGP Peers

Hi Joe,

You can manipulate bgp path selection (in your case) by defining Local Preference for each BGP Peer. the highest the more prefered.

you can either set a default local preference for ur Peers or use route-maps to define Local_perf for a set of prefixes.

you can find more:
