IPv6 Training (Cisco) - IPv6 Delegating Router Configuration

Hours to delegate to a Cisco router with the interface to the valley, like a router (DHCPv6 server) that leads Prefix Delegation for a given request Router (DHCP clients) will act, and also for a group of RR (DHCP client) using a DHCP server for IPv6 pool configuration, you must perform the following 10 steps:

1. Router> Enable
2. Router # configure terminal
3. Router (config) # IPv6 dhcp pool pool name
4. Router (dhcp-config) # domain-name domain
5.Router (dhcp-config) # dns-server IPv6 address of DNS server
6. Router (dhcp-config) # prefix-delegation client ipv6-prefix/prefix-length-DUID [IAID] [Life]
7. Router (dhcp-config) # prefix-delegation pool pool name [Lifetime (valid for life | life preferred)]
8. Router (dhcp-config) # exit
9. Router (config) # interface type number
10. Router (config-if) # IPv6 DHCP server pool name

Steps explained

Step 1: Router> enable

If the router into PrivilegedExec mode

Stage 2: router # configure terminal

If the router in Global Configuration Mode

Step 3: Router (config) # IPv6 local DHCP pool

If you configure a DHCP server configuration information for IPv6 pool with the name of "local use" and places in the DR router DHCP for IPv6 pool configuration mode.

Step 4: Configure the router (DHCP) # domain-name domain.com

Used to specify that all resource record (DHCP client) to use the domain name"domain.com".

Step 5: Configure the router (DHCP) # dns-server 2001:0 DC8: 4000:4000:: 52

Used to specify the DNS server (via the IPv6 address), which will be available upon request from the router (RR) / DHCP client.

Step # 6: config router (DHCP) # prefix delegation 2001:0 DC8: 1463:: / 48 0007000700F1A6E070D01

Used to specify that the prefix manually configured IPv6 numeric "2001:0 DC8: 1463:: / 48 is" only in the RR (DHCP client) to identify, has delegatedAssociation Identifier (IAID) from "0007000700F1A6E070D01. In other words: In this step, you determine that damage the DR (DHCP server), a specific IPv6 prefix to a specific RR (DHCP client).

Step 7: config router (DHCP) # domain-prefix-prefix-delegation pool life Pool 3600 60

Used to indicate that serve the IPv6 local prefix with the name "domain"-prefix-pool "for IPv6 Prefix Delegation for the RRS (DHCP client) observation period. In other words: In this step, you definedelegation that the router (DR), the domain "-prefix-pool", to delegate IPv6 prefixes to all other applicants router (RR).

Now, in case you wonder if "life" of the word is used to configure the IPv6 prefix length. But remember, if you use the word "life" with the prefix "pool delegation of power," is to configure the valid "Life" (3600) and the preferred one-off "(60) options.

The "good" life-cycle (3600) displays the time the option ispermitted (in seconds) that an IPv6 prefix by prefix delegation remains Pool "Request Router (RR), using valid, and the preferred one-off (60) switch is used to indicate the time allowed (in seconds) that the prefix IPv6 to be a RR from the prefix-delegation-pool "on vacation RR preferred.

Step # 8: config router (DHCP) # exit

Permission to leave the router DHCP pool configuration for IPv6, and enter global configuration mode.

Step 9:Router (config) # interface serial 0 / 0

Allows the DR-configuration mode for interface serial 0 / 0 interface.

Step # 10: Router config (-if) # ipv6 prefix DHCP server-delegation pool

DR says the router serial 0 / 0-interface, which is like a DHCPv6 server and implement the IPv6 local prefix with the name "domain"-prefix-pool "for use prefix delegation. Another way of saying, This is in step 10, you enable the DHCP for IPv6Service to the serial 0 / 0 interface that goes to the IPv6 prefix with the name of "local" domain-prefix-pool "for the prefix delegation's request for the use of RR.
