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.
35.55 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:
Switch(config-router)#neighbor 10.1.1.66 enforce-multihop
35.56 neighbor filter-list
Command: neighbor {<ip-address>|<TAG>} filter-list <.LINE> {<in>|<out>}
no neighbor {<ip-address>|<TAG>} filter-list <.LINE> {<in>|<out>}
Function: Access-list control for AS-PATH. The “no neighbor {<ip-address>|<TAG>} filter-list
<.LINE> {<in>|<out>}” cancels the AS-PATH access-list control.
Parameter: <ip-address>: Neighbor IP address.
<TAG>: Name of peer group.
<LINE>: AS-PATH access-list name configured through ip as-path access-list <.LINE>
<permit|deny> <LINE>.
Default: Not configured.
Command Mode: BGP route mode and address list mode.
