Border nodes link

taytibob — Fri, 09 Oct 2020 02:50:38 GMT

Very simple question :

If I have 2 border nodes with 2 links between them

Is the configuration between the two nodes going to be automated by dnac as an l2 portchannel or an l3 portchannel?

Or should i configure it myself ?

Thanks

It’s Manual configuration.. No automation between two borders..

Ok. Then what's the recommendation l2 or l3 ?

Hi,

Firstly, Per VRF ibgp neighborship between the two borders is required only if your northbound connections arent full mesh.

If your borders are C9K switches, then a Layer 2 Port-channel(trunk) with Per VRF iBGP running on SVI would suffice...
