Cisco vrf route leak
WebI've found an interesting feature at Cisco IOS XR platform that allows you to leak routes between global routing table and VRF. Actually it can be used for combination of MPLS VPN + Internet Acess via VPN, if Internet is routed via Global RIB. It looks like the configuration is pretty easy: RP/0/0/CPU0:R2#sh rpl route-policy IPv4_TO_DEF_VRF Webname_alias - (Optional) Name Alias of the Inter-VRF Leaked Route object. leak_to - (Optional) A block representing the attributes of Leak Routes for the Inter-VRF Leaked Route object. Type: Block. vrf_dn - Distinguished name of the destination VRF object, which is mapped to the Inter-VRF Leaked Route object.

You can import IP prefixes from the global routing table (the default VRF) into any other VRF by using an import policy.

You can also enable the VRFs in the EVPN fabric to access shared services in a specific VRF.
