Re: evpn with vrf (change to evpn inside inet.0 and igp advertise evpn /32's)
Oh dang, hang on... I just removed irb.0 from vrf and allowed it to sit in
inet.0 global table... and I DO see the evpn routes in inet.0 now...

So I think my question is actually this... when I have evpn with irb inside
vrf, MP-iBGP advertises all those evpn /32's to the other remote pe's in
that vrf. Great. But with epvn irb inside inet.0 , how do I get something
like ospf to do the same ? how do I get ospf to advertise all those evpn
/32 host routes ?

I would think this is what I would need in order to have the efficient
routing to the evpn hosts in a certain data center that spreads across many
dc's.... is, I would need the igp to advertise those epvn /32's throughout
the domain.

Re: evpn with vrf (change to evpn inside inet.0 and igp advertise evpn /32's) [ In reply to ]
I think I got it. This works to get evpn host routes into ospf. Is there a
better way ?

set policy-options policy-statement my-ospf-export-policy term 1 from
protocol evpn

set policy-options policy-statement my-ospf-export-policy term 1 then accept

set protocols ospf export my-ospf-export-policy

After putting the above evpn ospf export on an evpn pe, I see this on a
non-evpn ospf router across the network...
