Example 8-11 Output of show ip ospf virtual-links Command (Continued)
Index 2/3, retransmission queue length 0, number of retransmission 1
First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
Last retransmission scan length is 1, maximum is 1
Last retransmission scan time is 0 msec, maximum is 0 msec
The remote end of the virtual link is 192.16.100.3. The transit area is area 20 through Serial 0.
The OSPF cost of the virtual link is 64.
OSPF interfaces can be verified by using the show ip ospf interface command, as shown in
Example 8-12. For Router 3, the Ethernet interface is labeled as a BROADCAST Type with a
cost of 10. The Frame Relay interface is POINT_TO_POINT with a cost of 64 (for a T1). The
default Hello interval is 10 seconds and the dead time interval is 40 seconds. The priority for
the Ethernet interface is 10, and Router 3 is the DR router.
