Router Advertisements for IPv6
The following section provides a list of commands to configure the router advertisements messages.
Note: Local interface prefixes are not advertised automatically. A prefix is advertised only if it is explicitly configured.
To set the managed address configuration flag in the IPv6 router advertisements:
configure interface cable-mac <mac> ipv6 nd managed-config-flag [no]
To set the other stateful configuration flag in the IPv6 router advertisements:
configure interface cable-mac <mac> ipv6 nd other-config-flag [no]
To set the maximum (from 4 to 1800 seconds) and minimum (3 or 4 seconds) interval for neighbor solicitation
retransmissions:
configure interface cable-mac <mac> ipv6 nd ra interval <4-1800> <3-4> [no]
To set the lifetime for the router advertisement on the specified interface:
configure interface cable-mac <mac> ipv6 nd ra lifetime {0 | <4-9000>} [no]
Where:
0 indicates that the C4/c CMTS is not the default router and 4-9000 is the range in seconds of the lifetime
value.
DHCPv6 Relay Agent
To configure the DHCP relay destination for IPv6 on the specified interface.
configure interface cable-mac <mac[.sub-int]> ipv6 dhcp relay destination <ipv6-addr> [cable-modem |
host | any]
Basic Configuration Script
The following set of commands represents a minimal configuration script. This script does the following:
Instructs IPv6-capable modems on cable-mac 1 to attempt registration in IPv6 mode.
Shuts down cable-mac 1
Allows the C4/c CMTS to use IP Multicast DSID-based Forwarding (MDF)
Restores cable-mac 1 to service in order to cause the configuration change to take effect
