Configuring BGP EVPN Route Maps

Route maps can be used in the inbound or outbound direction for BGP peers for EVPN routes. When a route map is applied to a BGP peer, a ROUTE REFRESH message is sent. This results in the remote peer resending all the EVPN routes. If a route is already learned from a peer, the route map is applied. This results in the route being denied or the matching condition not being found. The learned route is then removed.

The following task creates a route map instance and specifies that the EVPN route type for the route map instance is 2. Only Type-2 routes are denied for the route map instance.

Enter global configuration mode.
```
device# configure terminal
```

Create a route map instance and allow a matching pattern.
```
device(config)# route-map myroutemap deny 1
```

Permit other EVPN routes.

device(config)# route-map myroutemap permit 2

Configure the route map to match on the specified prefix.
```
device(config-routemap myroutemap)# match evpn-route-type 2
```
Only Type-2 routes (MAC/IP advertisement routes) are denied and all other route types (Ethernet Auto-Discovery (A-D) routes, Inclusive Multicast Ethernet Tag (IMET) routes, Ethernet Segment routes and IP Prefix route) are permitted. For full details on these EVPN routes, refer to the match evpn-route-type command in the RUCKUS FastIron Command Reference.

The following example specifies that the EVPN route type for a route-map instance is 2. Only Type-2 routes are denied for the route map instance. Other EVPN routes are permitted.

device# configure terminal 
device(config)# route-map myroutemap deny 1
device(config)# route-map myroutemap permit 2
device(config-routemap myroutemap)# match evpn-route-type 2

The following example configures the EVPN prefix name to be used for MAC address filtering for a route map instance called "myroutemap".

device# configure terminal
device(config)# ip evpn-prefix-list deny 02e0.52cb.55c8
device(config)# ip evpn-prefix-list deny 02e0.52cb.55c9
device(config)# ip evpn-prefix-list plist permit any
device(config)# route-map myroutemap permit 1
device(config-routemap myroutemap)# match ip adddress evpn-prefix-list plist
