User Guidelines
If a neighbor does not respond to an initial TCP connection attempt, the
switch retries three times. The first retry is after the retry interval configured
with neighbor connect-retry-interval. Each subsequent retry doubles the
previous retry interval. So by default, the TCP connection is retried after 2, 4,
and 8 seconds. If none of the retries is successful, the adjacency is reset to the
IDLE state and the IDLE hold timer is started. BGP skips the retries and
transitions to IDLE state if TCP returns an error, such as destination
unreachable, on a connection attempt. The VLAN interface must also be
specified if a link-local address is specified.
Command History
Introduced in version 6.2.0.1 firmware.
Updated in version 6.3.0.1 firmware.
Example
console(config-router)#neighbor FE80::0202:B3FF:FE1E:8329 interface vlan 10
connect-retry-interval 10
neighbor default-originate (BGP Router
Configuration)
To configure BGP to originate a default route to a specific neighbor, use the
neighbor default-originate command in BGP Router Configuration mode.
Syntax
neighbor { ip-address | ipv6-address [interface interface-id ]} default-
originate [route-map
map-name ]
•
interface-id —A routing interface identifier (VLAN interface).
•
ip-address —The neighbor’s IPv4 address.
•
ipv6-address —The neighbor’s IPv6 address. If the neighbor’s IPv6 address
is a link local address, the local interface must also be specified.
•
map-name —(Optional) A route map may be configured to set attributes
on the default route advertised to the neighbor.
