Concept Guide
redistribute ospf process-id [match external {1 | 2} | match internal] [metric-type {external
| internal}] [route-map map-name]
Congure 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 congured route map.
Enabling Additional Paths
The add-path feature is disabled by default.
NOTE: Dell EMC Networking OS recommends
not
using multipath and add path simultaneously in a route reector.
To allow multiple paths sent to peers, use the following commands.
1 Allow the advertisement of multiple paths for the same address prex 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 specied neighbor/peer group to send/ receive multiple path advertisements.
CONFIG-ROUTER-BGP mode
neighbor add-path
NOTE
: The path-count parameter controls the number of paths that are advertised, not the number of paths that are
received.
Redistributing iBGP Routes into IGP
Dell EMC Networking OS supports redistributing iBGP routes into an Internal Gateway Protocol (IGP), such as, OSPF and IS-IS.
NOTE
: When you enable redistribution of iBGP routes into an IGP, ensure that you use route maps to control what prexes are
redistributed. Redistributing all iBGP routes can create a loop in the network. After conguring the bgp redistribute-
internal command, use the clear ip BGP * command to clear all BGP sessions.
Redistribute iBGP routes.
ROUTER BGP, ROUTER BGP-address-family, ROUTER BGP-address-family-IPv6, IPv4 VRF mode, and IPv6 Unicast VRF mode
bgp redistribute-internal
The following is an example conguration of redistributing iBGP routes into OSPF with the default VRF:
!
router ospf 100
router-id 1.1.1.1
network 10.10.10.0/24 area 0
redistribute bgp 65535 route-map bgp2ospf4
!
ipv6 router ospf 1
router-id 1.1.1.1
redistribute bgp 65535 route-map bgp2ospf6
Border Gateway Protocol (BGP)
