– metric value: The value is from 0 to 16777215. The default is 0.
– map-name: name of a configured route map.
• Include specific OSPF routes in IS-IS.
ROUTER BGP or CONF-ROUTER_BGPv6_ AF mode
redistribute ospf process-id [match external {1 | 2} | match internal]
[metric-type {external | internal}] [route-map map-name]
Configure the following parameters:
– process-id: the range is from 1 to 65535.
– match external: the range is from 1 or 2.
– match internal
– metric-type: external or internal.
– map-name: name of a configured route map.
Enabling Additional Paths
The add-path feature is disabled by default.
NOTE: In some cases, while receiving 1K same routes from more than 64 iBGP neighbors, BGP
sessions holdtime of 10 seconds may flap. The BGP add-path does not update packets for
advertisement and cannot scale to higher numbers. Either reduce the number of routes you add or
increase the holddown timer value.
To allow multiple paths sent to peers, use the following commands.
1. Allow the advertisement of multiple paths for the same address prefix without the new paths
replacing any previous ones.
CONFIG-ROUTER-BGP mode
bgp add-path [both|received|send] path-count count
The range is from 2 to 64.
2. Allow the specified neighbor/peer group to send/receive multiple path advertisements.
CONFIG-ROUTER-BGP mode
neighbor add-path
3. Configure the maximum number of parallel routes (multipath support) BGP supports.
CONFIG-ROUTER-BGP mode
max-path number
The range is from 2 to 64.
NOTE: The path-count parameter controls the number of paths that are advertised, not the
number of paths that are received.
