Hi all,

Any thoughts on Symmetric IRB?

Hi all,

With EVPN, we can have symmetric routing scenarios with no BD common between 
two tunnel end points (VTEPs in case of EVPN VxLAN).
In this draft the VNIs mentioned correspond to Bridge Table (BT).

How does this work in the above scenario?
Should BFD be carried on L3 VNI’s (with inner SRC MAC as router-mac of VTEP)? . 
It is not explicit in the draft though.

Regards,
Vinayak
