Can BGP be Routed Between 2 SVI's

[timhudson55]

Hello, 

Normally, BGP s routed between layer 3 interfaces with networks advertised and such. However, I was wondering if it is possible to use BGP between 2 Vlan addresses. For example:

In the attached diagram, I am hoping to use it between each site's own VLAN. Each of these sites needs to communicate with the 'Core' site and not with each other. We are hoping to do all of this without routed ports on the uplink interfaces, hence the SVI question.

Is this possible?

Many thanks for reading and for any responses!

An SVI is just another L3 interface so yes you can peer using SVIs if that is what you want.

Thank you so much! Would I just add these as

 IPv4 address-peers 

and it should just work?

Just configure it as you would normally so yes you use the IPs assigned to the SVIs.

Hi Tim,

Yes you can use SVI interfaces IPs... Please just make sure that the peer IPs are reachable via the global routing table.

Thanks,
