EMC Networking OS Command Line Reference Guide.
Version Description
9.14(0.1) Introduced on the S3048–ON, S4048–ON, S4048T-ON, S6010–ON, and Z9100–
ON.
Usage
Information
After configuring the bgp redistribute-internal command, use the clear ip bgp *
command to clear all BGP sessions. If you don’t clear all BGP sessions, route redistribution happens only
for new routes.
NOTE: When you enable redistribution of iBGP routes into an IGP, ensure that you use route maps to
control what prefixes are redistributed. Redistributing all iBGP routes can create a loop in the
network.
Example
Router(config)# router ospf 10
Router(config-router_ospf)# redistribute bgp 10 route-map bgp_2_ospf
Router(config-router_ospf)# exit
DellEMC(conf)# router bgp 10
DellEMC(conf-router_bgp)# bgp redistribute-internal
Caution: Might cause routing loops; please use prefix-list to restrict
the prefixes
Router(config-router_bgp)# end
Router# clear ip bgp

Syntax
