Syntax Description
This command has no arguments or variables.
Default
Enabled.
Usage Guidelines
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 it's way to it's 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 will forward 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.
Example
The following command enables processing of the strict source route IP option:
enable ip-option strict-source-route
