Hi Georg, Here is what our config looks like:   Primary DC: route-map NO-EXPO permit 10 set community no-export ip as-path access-list 10 permit ^$ router bgp 65200 bgp router-id x bgp always-compare-med bgp log-neighbor-changes timers bgp 15 45 ! address-family ipv4 redistribute eigrp 100 neighbor ISP1 peer-group neighbor ISP1 remote-as 65001 neighbor ISP1 fall-over neighbor ISP1 default-originate neighbor ISP1 advertisement-interval 5 neighbor ISP1 soft-reconfiguration inbound neighbor ISP2 peer-group neighbor ISP2 remote-as 16696 neighbor ISP2 fall-over neighbor ISP2 default-originate neighbor ISP2 advertisement-interval 5 neighbor ISP2 soft-reconfiguration inbound neighbor ISP2 route-map NO-EXPO in neighbor ISP2 filter-list 10 out Secondary DC: router bgp 65300 bgp router id x neighbor ISP1 remote-as 65001 neighbor ISP2 remote-as 16696 redistribute eigrp x redistribute ospf x redistribute static   The NO-EXPO and filter list were there to prevent our device from becoming a transit between MPLS providers. That config will be applied to the secondary DC shortly.   The primary DC will be the preferred path for 10.1.0.0/16 and backup path for 10.2.0.0/16 The secondary DC will be the preferred path for 10.2.0.0/16 and backup path for 10.1.0.0/16   Thanks,   Waqas ...

Thanks Richard, Is there an example I could follow for this? Say I have the primary datacenter with AS 65200 and secondary datacenter AS 65300 They both need to advertise 10.1.0.0/16 and 10.2.0.0/16. The primary datacenter will advertise 10.1.0.0/16 as the preferred path and 10.2.0.0/16 as the lesser preferred path. The secondary datacenter will advertise 10.1.0.0/16 as the lesser preferred path and 10.2.0.0/16 as the preferred path. What would the route map look like and how would it apply to the neighbor in the inbound or outbound? ... View more

That is what I figured. Although I am a bit disappointed that OSPF and EIGRP on the NX-OS platform doesn't have this capability. ... View more

Hi Georg, I think it would be easier to use bgp instead in this scenario: router bgp 100 router-id 10.170.253.1 address-family ipv4 unicast network 10.170.72.100 mask 255.255.255.255 network 10.170.72.101 mask 255.255.255.255 network 10.170.72.102 mask 255.255.255.255 network 10.170.72.103 mask 255.255.255.255 Regards, Waqas ...

Thanks for the reply Georg, This is all within the same area. However I only want to advertise 4 IPs in VLAN 72 at each site which is a /24. Distribute list doesn't exist on the Nexus platform. Regards, Waqas ... View more

Not that I am aware of but I think it was chosen because it was fairly recent. I posted the config in a reply below. There is quite a bit of config on it for ISE on all of our devices. We have this same version 15.2 running on all the other 3750X stacks in our building. This is the only switch having this issue. Unfortunately our support is expired so we can't get TAC to help with it. ... View more
