router

Profile Config Commands

Enables dynamic routing (BGP and/or OSPF) and enters the routing protocol configuration mode

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000
Note

Note

BGP is supported only on RFS4000, NX7500, and NX9500 model controllers and service platforms.

The NX9500 service platforms do not support OSPF routing.

The access points only support OSPF routing.

Syntax

router [bgp|ospf]

Parameters

router [bgp|ospf]
router Enables dynamic routing and enters the routing protocol configuration mode
bgp Enables BGP dynamic routing and configures relevant settings

BGP is an inter-ISP routing protocol, which establishes routing between ISPs. ISPs use BGP to exchange routing and reachability information between AS (Autonomous Systems) on the Internet. BGP uses TCP as its transport protocol, eliminating the need to implement explicit update fragmentation, retransmission, acknowledgement, and sequencing.

Routing information exchanged through BGP supports destination based forwarding only. It assumes a router forwards packets based on the destination address carried in the IP header of the packet.

An AS is a set of routers under the same administration that use Interior Gateway Protocol (IGP) and common metrics to define how to route packets within the AS.

For more information on dynamic BGP routing configurations, see Border Gateway Protocol .

ospf Enables OSPF dynamic routing and configures relevant settings. Changes configuration mode to router mode

OSPF is a link-state IGP. OSPF routes IP packets within a single routing domain (autonomous system), like an enterprise LAN. OSPF gathers link state information from neighbor routers and constructs a network topology. The topology determines the routing table presented to the Internet Layer which makes routing decisions based solely on the destination IP address found in IP packets.

For more information on dynamic OSPF routing configurations, see Router Mode.
