Enables processing of the strict source route IP option in the IPv4 packet header.
This command has no arguments or variables.
This enables the switch to forward IP packets that have the strict source route IP option (0x89) enabled.
Source routing is used when a sending host specifies the router interfaces that the packet must traverse on its way to its destination.
When strict source routing is used, it means that the packet must use the exact path of routers that lie in the designated router path.
With strict source routing enabled, the switch forwards IP packets with the strict source route option enabled, only if the switch's IP is in the designated list and as long as the next hop in the list is directly attached to one of the router's interfaces.
The following example enables processing of the strict source route IP option:
# enable ip-option strict-source-route
