Trying to work out configs for the followingâ¦(Big Iron and Cisco 3725).
Have a customer with a new Metro-E feed from us and a T1 from Sprint that wants to use BGP for failover. He has a class C from Sprint and wants that to be the advertised IP space. But, since ours has more bandwidth, he wants us to be the primary route - don't think that affects MY config, just putting it out there since his class C is a Sprint subnet.
This is my 2nd Metro-E and will terminate in a Big Iron switch in the same port as the first Metro-E (NOT tagged by AT&T). The 1st (and only at the moment) is configured with a /30 - 1 IP in Big Iron (untagged VLAN) and 1 in customer Pix (no VLAN).
The Big Iron connects to my Cisco 3725 Edge router on a private 10. network. Big Iron has default route of 3725 for all traffic.
The new Metro-E will obviously have to be tagged. I'll need to create a new VLAN on the Big Iron using the same port as the existing untagged VLAN. Will need help with that. Will probably want to go ahead and tag the 1st one as well to be consistent. Can address the Pix later.
The bigger issue is that this subnet is NOT on the edge 3725 router so how will BGP know about it? Would using a /29 and adding a VLAN on the Cisco work?
Customer AS 11111 has T1 from Sprint - IP's 18.104.22.168/24.
Will get Metro-E from me (AS 22222) - IP 22.214.171.124/29 (or 126.96.36.199/30 if it helps).
Metro-E terminates in my Layer 3 switch.
Switch connects to edge via private network.
