IES IPv6 IP interfaces provide IPv6 connectivity in the routing base instance. It can be used to connect IPv6 networks over an IPv4 cloud using the IPv6 Provider Edge Router over MPLS (6PE) functionality. For more information about the 6PE, see the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Router Configuration Guide, ‟IPv6 Provider Edge Router over MPLS (6PE)”.
IPv4 and IPv6 route table lookup entries are shared.
A separate route table (or a block in the route table) is used for IPv6 /128-bit prefix route lookup. A limited amount of IPv6 /128 prefixes route lookup entries is supported. The software enables lookups in this table by default (that is, no user configuration is required to enable Ipv6 /128-bit route lookup). A limited amount of IPv6 /128 prefixes route lookup entries is supported.
