enable ip option loose-source-route

enable ip option loose-source-route


Enables processing of the loose source route IP option in the IPv4 packet header.

Syntax Description

This command has no arguments or variables.



Usage Guidelines

This enables the switch to forward IP packets that have the loose source route IP option (0x83) enabled.

Source routing is used when a sending host specifies the router interfaces that the packet must traverse on it's way to it's destination.

With loose source routing enabled, the packet is forwarded if the routing table has a reverse path to the source IP address of the packet.


The following command enables processing of the loose source route IP option:

# enable ip-option loose-source-route
