Description
Specify the behavior for IRB interfaces defined as default gateways in an EVPN fabric.
In
an EVPN-VXLAN environment with multihoming, you might use multiple EVPN
routing instances on peer provider edge (PE) devices that share an Ethernet
segment (ES). When you configure anycast gateways with this statement, we
don’t support mixing the default behavior (same as the
advertise
option) with the
no-gateway-community
option on the links that
participate in the same ES.
As a result, if you configure the default-gateway
statement
with the no-gateway-community
option in any EVPN routing
instances on any peer PE device that share an ES, you must configure this
statement:
-
In all the routing instances that share the ES on a PE device,
-
On all the peer PE devices that share the ES,
-
Only with either the "no-gateway-community" option or the "do-not-advertise" option.
Options
advertise | Advertise the default gateway MAC address. This is the default behavior. |
do-not-advertise | Don't advertise the default gateway MAC address. |
no-gateway-community | Advertise virtual gateway addresses and IRB MAC addresses to EVPN peer devices so that Ethernet-only PE devices learn those MAC addresses. |
