Layer 3 Routing Commands 1286
User Guidelines
If a neighbor does not respond to an initial TCP connection attempt, the
N3000/N4000 Series 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.
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 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 ]
• 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.
•
route-map map-name —(Optional) A route map may be configured to set
attributes on the default route advertised to the neighbor.
Default Configuration
No default is originated by default.
