[c-nsp] VPLS BGP Signaling

[Mohammad Khalil]

As we are in the talk of l2vpns , I have searched on google for configuration for evpn but for Cisco I did not find good documentation regarding it , did anyone tried it before and can share?
Thanks

Thanks all , I have figured it out It was the ve id on both routers , configured similar , when I changed it on CSR2 it worked :)

Hi Nick/AllSorry for the bad format
Is it readable now?

Hi all
I have two CSR1000v boxes which am trying to establish several VPLS combinations for connectivity between two switches
All combinations worked perfectly except for BGP signaling (all the previous setups depend on LDP as a signaling
 protocol)
