f.
IPv6 multicast is currently not supported except for basic IPv6 functionality (DHCPv6, ND/RD, etc.). Non-basic IPv6
multicast is blocked.
g.
Packets that have the IPv6 loopback address (::1) as their source or destination IP address are dropped.
4.
The Cable Source Verify feature can also be used to verify the source IPv6 address of packets originating from a CPE.
5.
The C4/c CMTS supports standard IPv6 ACLs and extended IPv6 ACLs.
IPv6 Configure Commands
The following section provides a list of commands used to configure and enable IPv6 routing on the C4/c CMTS.
Note: The IPv6 configuration commands do not support subinterfaces. To configure the IPv6 IP address for the specified
interface:
configure interface gigabitethernet <slot>[/port.[.subif]] ipv6 address <addr> [eui-64] [link-local]
Where: <addr> Represents the IPv6 address/prefix.
To set the default limit for router advertisements and all IPv6 packets originated by the router:
configure ipv6 [no] hop-limit <number>
To display the usability status of interfaces configured for IPv6:
show ipv6 interface <WORD>
To establish static routes from the IPv6 route table:
configure ipv6 route <ipv6-address1>/<prefix-length> <ipv6-address2> [admin-distance <int>] [metric
<int>]
The previous command has an interface option if the next-hop address is a link-local address, as can be seen in the
following examples:
configure ipv6 route 2001:1234:0:1::/64 ?
<WORD> - Next Hop IPv6 address
