tBgpPeerNgFamily
1.3.6.1.4.1.6527.3.1.2.14.4.7.1.53
The value of tBgpPeerNgFamily specifies the types of routing
information to be distributed by the local side 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)', 'l2vpn (6)' and 'mcastVpnIpv4 (12)' 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.
