Hi, we are trying to get visibility into traffic at our remote site using netflow on a 9500. This remote site core switch has many VLANs and attaches to many 9300 access switches via trunks. All routing for the site is on the 9500. Traffic from and t...

Hi, I've been doing my research, watching vids on MP-BGP EVPN. All the documentation I have found thus far is referring to the Spine/Leaf design and config. I'm looking to L2 connect DCs over L3 (using a 9k in one DC and CSR100v in the other DC) by r...

Hello, I like to hear any thoughts on running OTV to extend L2 across DCs... We have 2, aging ASR1001s,License: Index 1 Feature: adventerprisePeriod left: Life time These routers provide our Internet connectivity. Do you think it would be advisable ...

Hello, looking for any solutions I can use to extend layer 2 networks over a layer 3 connection using Nexus 5500. I know QinQ and OTV, VXLAN are not supported, but could I use a GRE tunnel? Not sure that is supported on the Nexus either...having a ha...

Thx BB - do you config ingress and egress on VLAN interfaces or just in one direction? And why? Also, if I configure only on VLAN interfaces I would miss intra-VLAN flows, correct? For L2 traffic within the VLAN I would need to configure netflow on t...

Thank you, Joseph for you thoughtful post. You've given me some inspiration for design changes when we go to replace our Internet routers soon. Thank you, Pat

Thx a bunch, Sergiu!! Pat

Sergui, "Nexus 5500 does not support any overlay protocol, mainly because of the L3 capabilities, which are not built-in into the ASIC (carmel) - you need a L3 daughter card for it, compared with Nexus 5600 which supports quite a lot of features - th...

Sergiu, Actually, don't believe the 5500 platform supports fabric path - I think that was made available with the 5600s...Does the 5548 support any GRE tunneling that could carry some L2 traffic over an L3 connection? And, Note it doesn't have to be ...
