Switch(config-router)#neighbor 11.1.1.120 ebgp-multihop
on 11.1.1.120
Switch(config-router)#neighbor 10.1.1.64 ebgp-multihop
After this, switches in different segments will be able to create BGP neighbor relationship.
37.55 neighbor enforce-multihop
Command:
neighbor {<ip-address>|<TAG>} enforce-multihop
no neighbor {<ip-address>|<TAG>} enforce-multihop
Function:
Enforce the multihop connection to the neighbor. The “no neighbor {<ip-address>|<TAG>}
enforce-multihop” command cancels this configuration.
Parameter:
<ip-address>: Neighbor IP address.
<TAG>: Name of peer group.
Default:
Not enforced.
Command Mode:
BGP route mode and address-family mode
Usage Guide:
In fact the direct route can not be enforced to multihop, however will be treated as a multihop
connection with this configuration, namely the check originally only performed on IBGP and EBGP
of non-direct routes will be performed on all after this attribute set. The nexthop direct connected
check will not be performed at exit in enforce multihop conditions.
Example:
Enforce neighbor 10.1.1.66 as multihop connection.
Switch(config-router)#neighbor 10.1.1.66 enforce-multihop
37.56 neighbor filter-list
Command:
neighbor {<ip-address>|<TAG>} filter-list <.LINE> {<in>|<out>}
no neighbor {<ip-address>|<TAG>} filter-list <.LINE> {<in>|<out>}
