p2p OSPF convert to OSPF+(VRRP+MLAG)

[Chris1]

Ok we used to have a pretty simple setup
Site 1 -> OSPF p2p -> Core
Site 2 -> OSPF p2p
Site 3 -> OSPF p2p

That way we could redistribute our customers (/30) back to our Core so that the Core would be able to send traffic to the proper site, Worked Great.

Now our core is a MLAG of 2 switches, We spun up a VRRP on the vlan to the site betweent he mlag'd switches, set the default route on our Site switch to point at the VRRP and that works...

Put static routes for the /30's on both core switches in the mlag and customer traffic passes fine.

Now for the life of me i can't figure out what i'm doing wrong with the OSPF to get it working like it used to before, i can't use P2P because well it's 3 switches not 2.

All i want is for the remote sites to advertise their routes to both core switches.

I tried just leaving off the link-type point-to-point and the 3 switches appeared to get stuck in 2WAY and didn't receive/advertise anything.

The config i tried

Remote site had....
create ospf area 1.1.1.0
configure ospf area 1.1.1.0 stub summary stub-default-cost 10
configure ospf area 1.1.1.0 authentication simple-password Passwordy
configure ospf area 1.1.1.0 restart-helper both
configure ospf add vlan SITE1_BACKBONE area 1.1.1.0
configure ospf vlan SITE1_BACKBONE neighbor add 1.1.1.1
configure ospf vlan SITE1_BACKBONE neighbor add 1.1.1.2
configure ospf add vlan CUSTOMER1 area 1.1.1.0 link-type point-to-point passive

Core switch both had....
create ospf area 1.1.1.0
configure ospf area 1.1.1.0 stub summary stub-default-cost 10
configure ospf area 1.1.1.0 authentication simple-password Passwordy
configure ospf area 1.1.1.0 restart-helper both
configure ospf add vlan SITE1_BACKBONE area 1.1.1.0 link-type point-to-point
configure ospf vlan SITE1_BACKBONE neighbor add 1.1.1.3

As Stephen said above, in your case you will HAVE to have a core license on at least one of your XOS switches in order for the DR to be elected otherwise your will just sit in waiting mode.

[Stephen_Elliot1]

what licence do you have? you'll need a core licence to enable DR/BDR negotiation.

Have you tried restarting the osof process?
