Event Timeline
Added initial implementation here:
https://github.com/vyos/vyos-1x/pull/1904
We *might* have a problem with this as it seems like it might be buggy. I'll open up a case with FRR if you guys feel the need to do so.
The main thing I noticed is, when I enable OSPF LDP-IGP sync, under the interface we have a command "ip ospf mpls ldp-sync" that doesn't go away until there's a reboot. It's not there for ISIS for some reason.
I was able to test this for ISIS. I'll test OSPF hopefully tomorrow.
Here we have a topology where there's a VyOS router and a Juniper router. They are connected to each other on one specific interface.
Under normal operations the VyOS box looks like this for ISIS:
vyos@VyOS-BB2:~$ show isis interface detail | match "Interface|Metric" Interface: eth0, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth1, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth2, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: lo, State: Up, Passive, Circuit Id: 0x0 Metric: 10
When we reset the LDP session on the Juniper, it goes to this:
root@vMX-BB2-RE> clear ldp session 192.168.255.2 vyos@VyOS-BB2:~$ show isis interface detail | match "Interface|Metric" Interface: eth0, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth1, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth2, State: Up, Active, Circuit Id: 0x0 Metric: 16777214, Active neighbors: 1 Interface: lo, State: Up, Passive, Circuit Id: 0x0 Metric: 10
After a while, once LDP converges the metric comes back down:
vyos@VyOS-BB2:~$ show isis interface detail | match "Interface|Metric" Interface: eth0, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth1, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth2, State: Up, Active, Circuit Id: 0x0 Metric: 16777214, Active neighbors: 1 Interface: lo, State: Up, Passive, Circuit Id: 0x0 Metric: 10 vyos@VyOS-BB2:~$ show isis interface detail | match "Interface|Metric" Interface: eth0, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth1, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: eth2, State: Up, Active, Circuit Id: 0x0 Metric: 10, Active neighbors: 1 Interface: lo, State: Up, Passive, Circuit Id: 0x0 Metric: 10
Under normal operations the VyOS box looks like this for OSPF:
vyos@VyOS-BB1:~$ show ip ospf interface | egrep "eth|lo is up|Cost" eth0 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 10 eth2 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 10 lo is up Router ID 192.168.255.1, Network Type LOOPBACK, Cost: 0
When we reset the LDP session on the Juniper, it goes to this:
root@vMX-BB1-RE> clear ldp session 192.168.255.1 vyos@VyOS-BB1:~$ show ip ospf interface | egrep "eth|lo is up|Cost" eth0 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 10 eth2 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 65535 lo is up Router ID 192.168.255.1, Network Type LOOPBACK, Cost: 0
After a while, once LDP converges the metric comes back down:
vyos@VyOS-BB1:~$ show ip ospf interface | egrep "eth|lo is up|Cost" eth0 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 10 eth2 is up Router ID 192.168.255.1, Network Type POINTOPOINT, Cost: 10 lo is up Router ID 192.168.255.1, Network Type LOOPBACK, Cost: 0
