Step 4 Run:
vlink-peer router-id [ smart-discover | hello hello-interval | retransmit
retransmit-interval | trans-delay trans-delay-interval | dead dead-interval |
[ simple [ plain plain-text | cipher cipher-text ] | { md5 | hmac-md5 } [ key-id
{ plain plain-text | cipher cipher-text } ] | authentication-null | keychain
keychain-name ] ]
A virtual link is created.
This command must also be configured on the neighboring switch.
----End
Follow-up Procedure
After virtual links are created, different default MTUs may be used on devices provided by
different vendors. To ensure consistency, the MTU is set to 0 by default when the interface sends
DD packets. For details, see
MTU.

4.3.4 (Optional) Configuring a Route Selection Rule on the switch

You can configure the switch to comply with the route selection rule defined in RFC 1583 or
RFC 2328.
Context
RFC 2328 and RFC 1583 define the route selection rule differently. After OSPF is enabled on
the switch, specify a route selection rule based on the switch configuration. The switch complies
with the route selection rule defined in RFC 1583 by default. If the neighboring switch complies
with the route selection rule defined in RFC 2328, configure the local switch to comply with
that defined in RFC 2328. This allows all switches in the OSPF area to comply with the same
route selection rule.
Perform the following steps on the switch running OSPF.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospf [ process-id ]
The OSPF process view is displayed.
Step 3 Run:
undo rfc1583 compatible
The switch is configured to comply with the route selection rule defined in RFC 2328, not RFC
1583.
By default, the switch complies with route selection rule defined in RFC 1583.
