Hi
Is there any way design ASR + OTV Redundancy by routing instead EMM and bfd script ?
We have two router ASR and 2 ISP Link to redundancy.
So we now using EMM + bfd for control failover OTV link (active/standby) When Link ISP A down EMM action shutdown interface to down and script in router backup will be enable interface to handle the traffic
Some cause EMM + BFD doesn't work such bfd monitor link down and up same time but EMM not running some command to complete
therefore link no switch failover to backup
I dont know if any way to using routing control OTV link redundancy active/standby ?
or you have any idea or suggestion to improve
ref
bfd configure interval 300milisec *3

We have two router ASR and 2 ISP Link to redundancy.
what kind of links via internet or using MPLS or any other mode ?
how is your configuration looks like ?
we do have OTV deployment (but not using ASR, using nexus) - we follow below document and works for us.
even i have tested CSR in Lab works as expected.

Thank for reply

- We are using MPLS
now we do deployment OTV on ASR . Core Switch allow vlan to ASR Router
I agree with you to change OTV on Nexus not ASR

Hello,
post the running configs of your ASR/OTV edge routers, a First Hop Redundancy Protocol (FHRP) such as HSRP (Hot Standby Router Protocol) or VRRP (Virtual Router Redundancy Protocol) might work...
