disable bgp export vr
disable bgp export {vr} vr_name route_type {address-family} vpnv4
Description
For IPv4 and IPv6 routes, this command disables the PE router to
export and redistribute local VRF routes to remote PE routers through
BGP.
Syntax Description
vr
|
Specifies the source VPN VRF
of the exported routes. |
vr_name
|
Specifies the name of the
source VPN VRF. |
route_type
|
Specifies the source or origin
of the route types to be exported to remote PE routers. Valid Types:
blackhole, direct, and bgp. |
address-family
|
Specifies the address family
for the exported routes. Valid types are ipv4-unicast,
vpnv4. |
vpn4
|
Specifies that routes from the VRF are
exported as vpnv4 routes over MPBGP. |
Usage
Guidelines
This command disables a PE router to advertise learned routes
from CE routers to remote PE routers in a Service Provider's backbone. Executing this
command allows the PE router to convert VRF native IPv4 routes into VPN-IPv4 route,s and
advertise to all remote PE BGP neighbors as VPN-IPv4 routes.
- For Layer 3 VPNs, you must enter the disable bgp
export vr command in the context of the VRF that supports the Layer
3 VPN.
- When the export source is the Layer 3 VPN, you can specify direct, or remote-vpn
to disable route export to the VRF. The destination address family must be
ipv4‑unicast.
- This export command is applicable in Parent VR context only. If you execute it
in a VRF context, an error message is returned.
- The source VPN VRF must be a child of the Parent VR.
- BGP need not be added to a VPN VRF to export routes from a VPN VRF.
- The direction of where the redistribution is targeted is implicit on the
keywords used, For eg:- remote-vpn only applies to remote routes from PE
redistributed to CE, hence we cannot use it with address family vpnv4. Similarly
bgp only applies to EBGP routes from CE exported as VPN routes, hence we use it
only with address family vpnv4. Other sources such as “static” and “direct” are
redistributed both ways.
Example
The following command disables BGP to advertise a vpnv4 route
named "corp1_vpn_vrf":
disable bgp export "corp1_vpn_vrf" bgp address-family vpnv4
