So we have run into an interesting problem trying to do unnumbered OSPF between our MX routers and our EX switches.
We are running into an issue where we get the following on the EX:
OSPF packet ignored: netmask 255.255.255.255 mismatch from 10.10.10.10 on intf ae0.100 area 0.0.0.0
We then get this on the MX side:
OSPF packet ignored: netmask 0.0.0.0 mismatch from 10.10.10.11 on intf ae0.100 area 0.0.0.0
I'm not sure what the resolution would be here. We are running this just fine in other parts of our infrastructure and I'm not sure if there's a problem based on versions as we are running the 15.1 code base on the MX and the 17.2 code base on the EX series.
Seems odd that the unnumbered OSPF subnet mask for a /32 would be different between the two versions.
Here's the sanatized configuration of our MX side, the EX side looks identical.
mx# show interfaces ae0
vlan-tagging;
aggregated-ether-options {
minimum-links 1;
link-speed 10g;
lacp {
active;
periodic fast;
}
}
unit 100 {
vlan-id 100;
family inet {
unnumbered-address lo0.100;
}
}
mx# show interfaces lo0.100
family inet {
address 10.10.10.10/32;
}
mx# show protocols ospf area 0.0.0.0
interface ae0.100 {
interface-type p2p;
}
any input or information would be extremely helpful here!
Thanks
