Closed, ResolvedPublicBUG
Actions

Description

technically is possible to configure not just bonding interfaces as we now allow

vyos@PE-01# set interfaces bonding bond0 evpn uplink

it can be an ethernet interface , which is used by IGP :

FRR: 
Uplink/Core tracking¶

When all the underlay links go down the PE no longer has access to the VxLAN +overlay. To prevent blackholing of traffic the server/ES links are protodowned on the PE. A link can be setup for uplink tracking via the following zebra configuration -

evpn mh uplink
`
vyos@PE-01# set interfaces ethernet eth0 evpn

  Configuration path: interfaces ethernet eth0 [evpn] is not valid

I've tested and now is working correctly :

 vyos@PE-01# set interfaces ethernet eth1 evpn uplink
[edit]
vyos@PE-01# compare
[interfaces ethernet eth1]
+ evpn {
+     uplink
+ }

on frr output :

vyos@PE-01:~$ sudo vtysh -c "show interface eth1"
Interface eth1 is up, line protocol is up
