Offlist it was suggested to me that my typology is not very clear.
Perhaps a config snippet will help. Essentially, my two "ABRs" have one
foot in the OSPF world and the other foot in the IS-IS world. If needed,
I could run OSPF directly between the two ABRs. Both ABRs have direct
connections to each other. Here is a sample config snippet from ABR1.
The long term goal is to convert these OPSF only routers to IS-IS routers
and bring them into the ISIS domain:
[edit routing-instances Test]
ABR1# show
instance-type vrf;
interface xe-6/2/0.130;
interface xe-11/0/0.130;
interface xe-10/0/0.130;
interface lo0.130;
route-distinguisher 192.168.0.7:130;
vrf-import [ testin ];
vrf-export [ testout ];
vrf-table-label;
routing-options {
router-id 192.168.130.7;
auto-export;
}
protocols {
ospf {
reference-bandwidth 100g;
area 0.0.0.0 {
interface lo0.130 {
passive;
}
interface xe-6/2/0.130 {
description "Facing OSPF area - no IS-IS";
}
}
}
isis {
level 2 wide-metrics-only;
level 1 {
disable;
wide-metrics-only;
}
interface xe-11/0/0.130 {
description "Facing ABR2";
}
interface xe-10/0/0.130 {
description "Facing another IS-IS router";
}
interface lo0.130 {
passive;
}
}
}
