In access-uplink mode, IES IP interfaces associated with access-uplink SAPs support IPv6 addressing. IPv6 can be used for in-band management of the node using the IES IP interface.
IPv6 IES IP interfaces on access-uplink SAPs are only supported on 7210 SAS-D and 7210 SAS-Dxp.
On 7210 SAS-D and 7210 SAS-Dxp, IPv4 and IPv6 route table lookup entries are shared. Before adding routes for IPv6 destinations, route entries in the routed lookup table needs to be allocated for IPv6 addresses. This can be done using the config> system> resource-profile> router> max-ipv6-routes command. This command allocates route entries for /64 IPv6 prefix route lookups. The system does not allocate any IPv6 route entries by default and user needs to allocate some resources before using IPv6. For the command to take effect, the node must be rebooted after making the change. For more information, refer to the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Basic System Configuration Guide. A separate route table is used for IPv6 /128-bit prefix route lookup. A limited number of IPv6 /128 prefixes route lookup entries is supported on 7210 SAS-D. The software enables lookups in this table by default (that is, no user configuration is required to enable IPv6 /128-bit route lookup).
On the 7210 SAS-D and 7210 SAS-Dxp, IPv6 interfaces are created without allocating IPv6 route entries.
Following features and restrictions is applicable for IPv6 IES IP interfaces:
IPv6 interfaces supports only static routing.
Only port-based ingress QoS policies are supported.
IPv6 filter policies can be used on SAP ingress and egress.
Routing protocols, such as OSPFv3, and others are not supported.
A limited number of IPv6 /128 prefixes route lookup entries is supported.
