Ccna routing and Switching Complete Study Guide

Encapsulation TUNNEL, loopback not set

  Keepalive not set

  

Tunnel source 63.1.1.1, destination 63.1.1.2

  

Tunnel protocol/transport GRE/IP

    Key disabled, sequencing disabled

    Checksumming of packets disabled

  Tunnel TTL 255

  Fast tunneling enabled

  Tunnel transmit bandwidth 8000 (kbps)

  Tunnel receive bandwidth 8000 (kbps)

The 

show interfaces

 command shows the configuration settings and the interface sta-

tus as well as the IP address, tunnel source, and destination address. The output also shows 

the tunnel protocol, which is GRE/IP. Last, let’s take a look at the routing table with the 

show ip route

 command.

Corp#

sh ip route

[output cut]

     192.168.10.0/24 is subnetted, 2 subnets

C      192.168.10.0/24 is directly connected, Tunnel0

L      192.168.10.1/32 is directly connected, Tunnel0

     63.0.0.0/30 is subnetted, 2 subnets

C      63.1.1.0 is directly connected, Serial0/0

L      63.1.1.1/32 is directly connected, Serial0/0

The 

tunnel0

 interface shows up as a directly connected interface, and although it’s a 

logical interface, the router treats it as a physical interface, just like serial 0/0 in the routing 

table.
