Routed subscriber sessions

Enterprise IP VPNs often use BGP to exchange routing information, for example, between headquarters and branch offices. Providing BGP connectivity to an enterprise router via a residential access connection requires BGP peering over a BNG CUPS subscriber session. To configure this on the BNG CUPS UPF, use a static BGP neighbor that has as its neighbor address the fixed IPv4 or IPv6 WAN address of the subscriber session.

Example configuration

# configure service vprn 1000
    --- snip ---
    subscriber-interface "_tmnx_cups_1131076" fwd-service 2148278386 
    /fwd-subscriber-interface "_tmnx_cups_1131075" wan-mode mode128 
        description "default subscriber interface template"
        private-retail-subnets
        address 10.0.240.254/20
        ipv6
        exit
    exit
    bgp
        group "enterprise-1"
            neighbor 10.0.0.1
                family ipv4
                local-address 10.0.240.254
                type external
                local-as 65536
                peer-as 65501
            exit
        exit
        no shutdown
    exit
    no shutdown
