I just have a quick question here, I have 2 BGP connections a primary and backup terminating on the one router. In the pass the way I know how to deal with it is put them in a vlan in the terminating router and use the vlan to peer. That way if the primary goes down I still have connection via the back up. Now the person I'm working with informs me that since he created 2 /30 I don't need to run a vlan....how else do I get this to work? I've tried explaining to him but he will not change the 2 /30 into one /29 so I can to a vlan between the primary and secondary. If I had another router then I would put primary on one and secondary on the other. Thank you in advance
a /29 and one VLAN ID is valid. personally, I prefer 2 VLAN IDs and 2 subnets.
number of IPs used is same for 2 x /30 or 1 x /29. but U get out of it is protection against human error, when VLAN is removed form trunk for example or interface VLAN clean up by error.
