The error “Administratively disabled” means we need to enable SCP on the router with the command: Router(config)#ip scp server enable

According to this question, uRPF is running in strict mode because packets are dropped even

when that route exists in the routing table. Maybe packets are dropped because the receiving

interface is different from the interface the local router uses to send packets to that destination.

The ip verify unicast source reachable-via rx command enables Unicast RPF in strict mode.

To enable loose mode, administrators can use the any option (ip verify unicast source

reachable-via any). In loose mode, it doesn’t matter if we use this interface to reach the source

or not.

The allow-default option allows the use of the default

route in the source verification process.

From the output, we learned that R1 was trying to establish BGP neighbor relationship with R3 but failed. Both of them were using physical interface to establish neighbor relationship so wedon’t need the “… ebgp-multihop” command here. The only reasonable answer is R3 has not been configured to activate BGP neighbor relationship with R1.
