no neighbor { ip-address | ipv6-address [ interface interface-id ]} next-hop-
self
•
ip-address – The neighbor's IPv4 address.
ipv6-address [ interface interface-id ] – The neighbor's IPv6 address. If the
•
neighbor's IPv6 address is a link local address, the local interface must also
be specified.
Default Configuration
This is not enabled by default.
Command Mode
IPv6 Address Family Configuration mode
User Guidelines
When the next hop attribute in routes from external peers is retained,
internal peers must have a route to the external peer's IP address. This is
commonly done by configuring the IGP on the border router to advertise the
external (or "DMZ") subnet. The next-hop-self option eliminates the need to
advertise the external subnet in the IGP.
In IPv6 Address Family Configuration mode, the command accepts either an
IPv4 or an IPv6 address. For IPv6, BGP uses an IPv6 address from the local
interface that terminates the peering session. The VLAN interface must also
be specified if a link-local address is specified.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router-af)#neighbor FE80::0202:B3FF:FE1E:8329 interface vlan
10 next-hop-self
neighbor password
Use the neighbor password command to enable MD5 authentication of TCP
segments sent to and received from a neighbor, and to configure an
authentication key.
