1160 CHAPTER 76: OSPF CONFIGURATION COMMANDS

Description Use the vlink-peercommand to create and configure a virtual link.

Use the undo vlink-peercommand to remove a virtual link.

As defined in RFC2328, all non-backbone areas must maintain connectivity to the backbone. You can use the vlink-peercommand 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-delaykeyword.

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.
