Assigning the administrative distance to DHCPv6 static routes
To assign the administrative distance to DHCPv6 static routes installed in IPv6 route table for the delegated prexes on the interface, use
the ipv6 dhcp-relay distance command at the interface level. The administrative distance value has to be set so that it does not replace
the same IPv6 static route congured by the user.
device(config-if-eth-1/2/1)# ipv6 dhcp-relay distance 25
Syntax: [no] ipv6 dhcp-relay distance value
The value parameter is used to assign the administrative distance to DHCPv6 static routes on the interface. The range is from 1 to 255.
The default value is 10. If the value is set to 255, then the delegated prexes for this interface will not be installed in the IPv6 static route
table.
Use the no ipv6 dhcp-relay distance command to set the parameter to a default value of 10.

information
Enter the show ipv6 dhcp-relay delegated-prexes command to display information about the delegated prexes.

Syntax: show ipv6 dhcp-relay
delegated-prexes vrf vrf-name } { X:X::X:X/M | client-id client ipv6 address | interface interface-id }
The vrf vrf-name parameter is used to display the DHCPv6 delegated prexes for a specic VRF.
The X:X::X:X/M parameter is used to display the specied delegated prex information.
The client-idclient ipv6 address parameter is used to display the delegated prex for the specic client.
The interfaceinterface-id parameter is used to display delegated prexes for the specied outgoing interface.
Table 43 describes the elds from the output of show ipv6 dhcp-relay delegated-prexes command.
