1160 CHAPTER 76: OSPF CONFIGURATION COMMANDS
Description Use the vlink-peer command to create and configure a virtual link.
Use the undo vlink-peer command to remove a virtual link.
As defined in RFC2328, all non-backbone areas must maintain connectivity to the
backbone. You can use the vlink-peer command to configure a virtual link to
connect an area to the backbone.
Note that:
■The smaller the hello interval is, the faster the network converges and the more
network resources are consumed.
■A so small retransmission interval will lead to unnecessary retransmissions. A
big value is appropriate for a low speed link.
■You need to specify an appropriate transmission delay with the trans-delay
keyword.
The authentication mode at the non-backbone virtual link end follows the one at
the backbone virtual link end. The two authentication modes (MD5 or Simple) are
independent, and you can specify neither of them.
Related commands: authentication-mode, display ospf peer.
Examples # Configure a virtual link with the neighbor router ID 1.1.1.1.
