To configure a BGP EVPN
Steps
A 7750 SR, 7450 ESS, 7250 IXR, or 7950 XRS can generate Ethernet auto-discovery routes. When BGP EVPN is configured, a single AD per-ES route with the associated RD and a set of EVI route-targets is advertised.

On the equipment tree, right-click on an NE and choose Properties. The Network Element (Edit) form opens.
|
2 |
Click on the Globals tab, and then on the Service tab.
|
3 |
Click on the BGP tab, and then on the EVPN tab.

Configure the required BGP EVPN parameters. The following considerations apply:
-
The default Route Distinguisher Type is None. In this case, the RD is automatically built using the BGP-AD VPLS ID configured under the VPLS Site BGP tab. If you set the Route Distinguisher Type to Configured, then you need to provide an RD IP address.
-
The default AD per-ES routes advertisement type is EVI-RT, which specifies the option to advertise a separate AD per-ES route per service.
The EVI-RT Set advertisement type specifies the option to advertise a set of AD per-ES routes aggregating the route targets for all the services in the Ethernet segment. If you choose EVI-RT Set, then you need to specify the IP address part of the RD that is being used in the EVI-RT Set option.
-
To allow for both EVPN VXLAN and EVPN MPLS to be in an Admin Up state on the same VPLS, different BGP IDs should be assigned to VXLAN and MPLS.
-
If two EVPN VXLAN instances are created on the same VPLS, different BGP IDs should be assigned to each VXLAN.
-
To allow propagation of attributes to other owners in VPRN, enable the Attribute Uniform Propagation parameter.
-
To allow new BGP based selection for RT5 routes, enable BGP Path Selection parameter.
-
To ignore the D-PATH domain segment length, enable the D-Path Length Ignore parameter.
