Hi @lawrencepan,

you have an idea how the VyOS CLI commands should look like?

Viacheslav added a subscriber: Viacheslav.May 19 2021, 11:11 AM

@c-po
I propose to add "set routing-options x.x.x.x"
And also migrate protocols xxx route-map

set protocols bgp 65001 route-map RMAP
set protocols bgp|ospf|isis route-map RMAP

to

set routing-options import bgp|ospf|isis route-map RMAP
set routing-options nht resolve-via-default

Why move the protocol specific route map to a new CLI node? This makes no sense to me.

I would use: set system ip(v6) nht, as this node already exists

As I understand it a part of zebra, not specified to any protocol.
Maybe I'm wrong and we don't need it.

r6-roll(config)# ip protocol xxx route-map
