Use to enable checksum computation across a GRE tunnel.
Checksum computation is not supported for DVMRP tunnels.
Selecting this feature causes the E Series router to drop corrupted packets it receives
on the tunnel interface.
Example
host1(config)#interface tunnel gre:tunnel2
host1(config-if)#tunnel checksum
Use the no version to disable the checksum option.
See tunnel checksum.
Use to configure the remote end of the tunnel.
Specify either the IP address of an interface on the remote router or the hostname of
the remote router.
The IP address is the address for the destination interface.
The hostname is the name of the destination interface.
Example 1
host1(config)#interface tunnel dvmrp:tunnel2
host1(config-if)#tunnel destination 192.13.7.1
Example 2
host1(config)#interface tunnel dvmrp:tunnel2
host1(config-if)#tunnel destination remoteHost
Use the no version to remove the destination of a tunnel.
See tunnel destination.
Use to set the MTU for the tunnel.
Specify a value in the range 1024–10240 bytes.
Example
host1(config-if)#tunnel mtu 7500
Use the no version to restore the default, 10240 bytes.
See tunnel mtu.
Use to configure the source of the tunnel.
Specify either the primary IP address or the type and specifier of an interface.
Do not specify an unnumbered interface.
Example 1—Primary IP address
