Concept Guide

redistribute {connected | static} [route-map map-name]
Congure the map-name parameter to specify the name of a congured route map.
• Include specic ISIS routes in BGP.
ROUTER BGP or CONF-ROUTER_BGPv6_ AF mode
redistribute isis [level-1 | level-1-2 | level-2] [metric value] [route-map map-name]
Congure the following parameters:
– level-1, level-1-2, or level-2: Assign all redistributed routes to a level. The default is level-2.
– metric value: The value is from 0 to 16777215. The default is 0.
– map-name: name of a congured route map.
• Include specic 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]
Congure 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 congured route map.
Enabling Additional Paths
The add-path feature is disabled by default.
NOTE
: Note: In some cases, while receiving 1K same routes from more than 64 iBGP neighbors, BGP sessions holdtime of 10
seconds may ap. The BGP add-path does not update packets for advertisement and cannot scale to higher numbers. Either
reduce the number of routes added 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 prex without the new paths replacing any previous ones.
CONFIG-ROUTER-BGP mode
bgp add-path [send | receive | both] count
The range is from 2 to 64.
2 Allow the specied neighbor/peer group to send/ receive multiple path advertisements.
CONFIG-ROUTER-BGP mode
neighbor add-path
3 Congure the maximum number of parallel routes (multipath support) BGP supports.
CONFIG-ROUTER-BGP mode
max-path number
The range is from 2 to 64.
