tunnel source

Configuration Example

In this example, two GRE tunnel interfaces are configured on different virtual routers
of an E Series router. The source of the first tunnel interface matches the destination
of the second tunnel interface and vice versa.
NOTE: This example contains an ATM interface configuration for an ERX7xx model,
ERX14xx model, or ERX310 router that uses the slot/port format.

Configuration Tasks
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
host1(config)#interface tunnel dvmrp:boston-tunnel-1
host1(config-if)#tunnel source 192.10.2.1
Example 2 ATM interface on an ERX7xx model, ERX14xx model, or the ERX310
router that uses the slot/port format
host1(config)#interface tunnel dvmrp:boston-tunnel-1
host1(config-if)#tunnel source atm 5/0.12
Example 3 ATM interface on an E320 router that uses the slot/adapter/port
format
host1(config)#interface tunnel dvmrp:boston-tunnel-1
host1(config-if)#tunnel source atm 5/1/0.12
Use the no version to remove the source of a tunnel.
See tunnel source.
Configure a virtual router called boston that supports one end of the tunnel.
