Console(config-router)#
neighbor
ebgp-multihop
This command allows eBGP neighbors to exist in different segments, and
configures the maximum hop count (TTL). Use the no form to restore the default
setting.
Syntax
neighbor {ip-address | group-name} ebgp-multihop [count]
no neighbor {ip-address | group-name} ebgp-multihop
ip-address – IP address of a neighbor.
group-name – A BGP peer group containing a list of neighboring routers
configured with the neighbor peer-group command.
count – Maximum hop count. (Range: 1-255)
Command Mode
Router Configuration
Default Setting
eBGP neighbors must be located in the same segment.
Command Usage
â—† This command can be used to allow routers in different network segments to
create a BGP neighbor relationship.
â—† If this command is entered without specifying a count, the hop limit is set at
255.
â—† To avoid creating loops through oscillating routes, a multi-hop session will not
be established if the only route to a multi-hop peer is the default route.
Example
Console(config-router)#neighbor 10.1.1.64 ebgp-multihop 2
Console(config-router)#
