tBgpPeerNgVpnRemoteFamily 1.3.6.1.4.1.6527.3.1.2.14.4.7.1.54

The value of tBgpPeerNgVpnRemoteFamily indicates the types of routing information to be distributed by the remote end of this Peer of the BGP protocol. BGP was initially designed for the distribution of IPv4 routing information. Multi-protocol extensions and the use of a VPN-IPv4,VPN-IPv6, MVPN-IPv4 and L2-VPN address have been added to extend its ability to carry overlapping routing information. A 'vpnIpv4 (2)' address is a 12-byte value consisting of the 8-byte route distinguisher, RD, and the 4-byte ipv4 IP address prefix. The RD must be unique within the scope of the VPRN. This allows the IP address prefixes within different VRFs to overlap. 'ipv6 (3)', 'mcastIpv4 (4)', and 'l2vpn (6)' are multi-protocol extensions to BGP. A 'vpnIpv6 (5)' address is a 24-byte value consisting of the 8-byte RD, and 16 bytes for the IPv6 address. When both IPv4 and IPv6 VPRN services are enabled, the PE router uses the same RD for both address families. A 'l2vpn (6)' address is a 12-byte Virtual Switch Instance identifier (VSI-ID) value consisting of the 8-byte route distinguisher(RD) followed by a 4-byte value. A 'mvpnIpv4 (7)' address is variable size value consisting of the 1-byte route type, 1-byte length and variable size route type specific. Route type defines encoding for the route type specific field. Length indicates the length in octets of the route type specific field.
