peer advertise route-reoriginated (BGP-EVPN address family view)

Function

The peer advertise route-reoriginated command configures a device to send the routes that are regenerated in the EVPN or VPNv4/v6 address family to a BGP EVPN peer.

The undo peer advertise route-reoriginated command restores the default configuration.

By default, a device does not send the routes that are regenerated in the EVPN or VPNv4/v6 address family to a BGP EVPN peer.

Format

peer peerIpv4Addr advertise route-reoriginated { evpn { mac-ip | mac } | vpnv4 }

peer peerIpv4Addr advertise route-reoriginated evpn ip

peer peerIpv4Addr advertise route-reoriginated { evpn { mac-ipv6 | ipv6 } | vpnv6 }

peer peerIpv6Addr advertise route-reoriginated vpnv4

peer peerIpv6Addr advertise route-reoriginated vpnv6

peer peerIpv6Addr advertise route-reoriginated evpn ip

peer peerIpv6Addr advertise route-reoriginated evpn ipv6

undo peer peerIpv4Addr advertise route-reoriginated { evpn { mac-ip | mac } | vpnv4 }

undo peer peerIpv4Addr advertise route-reoriginated evpn ip

undo peer peerIpv4Addr advertise route-reoriginated { evpn { mac-ipv6 | ipv6 } | vpnv6 }

undo peer peerIpv6Addr advertise route-reoriginated vpnv4

undo peer peerIpv6Addr advertise route-reoriginated vpnv6

undo peer peerIpv6Addr advertise route-reoriginated evpn ipv6

undo peer peerIpv6Addr advertise route-reoriginated evpn ip

Parameters

Parameter	Description	Value
peerIpv4Addr	Specifies the IPv4 address of a peer.	It is in dotted decimal notation.
evpn	Re-encapsulates the received EVPN routes.	-
mac-ip	Re-encapsulates the IRB or ARP routes in received EVPN routes.	-
mac	Re-encapsulates MAC routes in received EVPN routes.	-
vpnv4	Re-encapsulates received VPNv4 routes.	-
ip	Re-encapsulates received prefix routes.	-
mac-ipv6	Re-encapsulates the IRBv6 or ND routes in received EVPN routes.	-
ipv6	Re-encapsulates received IPv6 prefix routes.	-
vpnv6	Re-encapsulates received VPNv6 routes.	-
peerIpv6Addr	Specifies the IPv6 address of a peer.	The prefix is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.

Usage Guidelines

Usage Scenario

Data Center Interconnection (DCI) provides solutions used to interconnect data centers. In DCI solutions, each DCI-PE re-encapsulates received EVPN or VPNv4/v6 routes before sending them to its peers.

After the EVPN routes that are received from the DC side and carry the VXLAN encapsulation attribute are regenerated on the DCI-PE, the DCI-PE advertises EVPN routes that carry the MPLS encapsulation attribute to the BGP EVPN peer on the DCI backbone network.
After the EVPN/VPNv4/VPNv6 routes that are received from the BGP EVPN/VPNv4/VPNv6 peer on the DCI backbone network and carry the MPLS encapsulation attribute are regenerated on the local DCI-PE, the local DCI-PE advertises EVPN routes that carry the VXLAN encapsulation attribute to the DC side.
In a scenario where an EVPN L3VPN over SRv6 interworks with a common L3VPN over MPLS, border leaves must be configured with the function to re-originate SRv6-encapsulated EVPN routes and advertise these EVPN routes to a BGP EVPN IPv6 peer upon receipt of VPNv4/VPNv6 routes carrying the MPLS encapsulation attribute.

Prerequisites

Route information exchange has been enabled between the local device and a specified peer using the peer enable command.
