Parameters None
Default Not configured
Command Mode ROUTER-BGP
Usage
Information
When an IGP protocol such as OSPF is configured to redistribute BGP, by default, only the eBGP routes
are redistributed. You can use this command to enable redistribution of iBGP routes in addition to external
BGP (eBGP) routes. This configuration is applicable only for IPv4 unicast and IPv6 unicast address family
modes, and it is not applicable for L2 VPN EVPN address family.
The no version of this command disables iBGP redistribution.
Example - Enable
redistribution of
IPv4 iBGP routes
in default VRF
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# address-family ipv4 unicast
OS10(configure-router-bgpv4-af)# bgp redistribute-internal
Example - Enable
redistribution of
IPv6 iBGP routes
in VRF "dell"
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# vrf dell
OS10(config-router-bgp-100-vrf)# address-family ipv6 unicast
OS10(configure-router-bgpv6-vrf-af)# bgp redistribute-internal

clear ip bgp
Resets BGP IPv4 or IPv6 neighbor sessions.
Syntax
clear ip bgp [vrf vrf-name] {ipv4–address | ipv6–address | * | interface
interface-type} [ ipv4 | ipv6 | soft in]
Parameters
● vrf vrf-name — (OPTIONAL) Enter vrf then the name of the VRF to clear IPv4 or IPv6 BGP
neighbor sessions corresponding to that VRF.
● IPv4–address — Enter an IPv4 address to clear a BGP neighbor configuration.
● IPv6–address — Enter an IPv6 address to clear a BGP neighbor configuration.
● * — Clears all BGP sessions.
● interface interface-type — Clears BGP information that is learned through an unnumbered
neighbor. Enter one of the following interface types:
○ ethernet node/slot/port[:subport] — Display Ethernet interface information.
○ port-channel id-number — Display port channel interface IDs, from 1 to 128.
○ vlan vlan-id — Display the VLAN interface number, from 1 to 4093.
● soft — (Optional) Enter to configure and activate policies without resetting the BGP TCP session
— BGP soft reconfiguration.
● in — (Optional) Enter to activate only ingress (inbound) policies.
Default Not configured
