host1#baseline ip interface pos 2/0
There is no no version.
See baseline ip interface
The router enables you to disable forwarding of packets on an SRP Ethernet interface.
Use to disable forwarding of packets on the SRP Ethernet interface.
The purpose of this command is to maintain router performance by maximizing the
CPU time available for routing protocols. Although you can allow data forwarding on
the SRP Ethernet interface, router performance will be affected.
You see an error message if you try to set this command for interfaces other than the
SRP Ethernet interface.
Example
host1(config-if)#ip disable-forwarding
Use the no version to enable forwarding of packets on the interface.
See ip disable-forwarding
IP packets are normally routed according to the destination address they contain based
on the routing table at each hop through a path. The originator or source of the
source-routed packets specifies the path (the series of hops) that the packets must
traverse; the source makes the routing decisions. The source can specify either of the
following types of source routing:
Strict-source routing specifies every hop that the packet must traverse. The specified
path consists of adjacent hops. The source generates an ICMP error if the exact path
cannot be followed. For example, for a path going from source router A to router B to
router C to router D, router A specifies a strict-source route as B, C, D.
Loose-source routing specifies a set of hops that the packet must traverse, but not
necessarily every hop in the path. That is, the specified hops do not have to be adjacent.
For example, for a path going from source router A to router B to router C to router D,
router A specifies a loose-source route as B, D or C, D, or B, C, D.
Use to enable forwarding of source-routed packets in a VR or VRF.
Forwarding is disabled by default in all VRs.

host1(config)#ip source-route
