Cisco EzVPN with OSPF

[saifuddin.miyaji]

Hi,

https://www.cisco.com/c/en/us/support/docs/security-vpn/ezvpn/118240-config-ezvpn-00.html#anc7

The above link works very well for Cisco EzVPN with EIGRP. I have tried the same with OSPF but it does not work. Could someone shed some light on this...how to make it work with OSPF.

Regards

Hi,

EZVPN is a legacy solution, it's no longer supported nor developed. The replacement solution is FlexVPN.

What is the actual issue with EZVPN?

Has the VPN been established and you just cannot form a routing adjacency?

Please provide your configuration for review and debugs.

Hi,

Yes, we are aware that EzVPN is obsolete but still certain features of this VPN compels us to use it instead of new FlexVPN.

"What is the actual issue with EZVPN?

Yes, the VPN is established and we can ping from one LAN to another. In fact, EIGRP is also working well. Just that OSPF does not form adjacency.

Along with the configuration defined in the above document, we have added the following for the HUB and spoke:

On HUB:

router ospf 100
router-id 10.0.0.1
network 192.168.0.0 0.0.0.255 area 0
neighbor 10.0.3.1
neighbor 10.0.2.1

On Spoke1:

router ospf 100
router-id 10.0.2.1
network 192.168.2.0 0.0.0.255 area 0
neighbor 10.0.0.1

It does not for the neighbor relationship

Curious to know which exact feature does EZVPN have that FlexVPN does not?

Without seeing the entire configuration, it'll be hard to replicate or determine where your issue is.
