7.
Configure VRRP backup groups for NAT and non-NAT users.
8.
Configure RBSs.
9.
Configure RBPs for NAT and non-NAT users.
10. Bind the RBPs to the interfaces from which NAT and non-NAT users go online.
Data Preparation
To complete the configuration on Routers A and B, you need the following data.
l
Name of a NAT instance and slot ID of the board to which the NAT instance is bound
l
Name, start IP address, and end IP address of a public NAT address pool
l
Name, gateway address, and address range of a private address pool for NAT users, name
of a NAT user group, and access domain names of NAT users
l
Names, gateway addresses, and address ranges of master and backup address pools for non-
NAT users, and access domain names of non-NAT users
l
NAT traffic distribution policy and conversion policy
l
BFD session name, peer IP address detected by BFD, and local and remote discriminators
of a BFD session
l
ID and virtual IP address of a VRRP backup group, VRRP priorities of devices in the VRRP
backup group and value by which a VRRP priority reduces, and preemption delay (only
for Router A)
l
Remote backup ID that associates an RBP with an RBS
l
NAT parameters, including logical IP addresses, logical interfaces, and logical host names
l
IDs of VLANs where VRRP is deployed, and range of VLANs to which NAT and non-
NAT users are bound
Procedure
Step 1
Create a NAT instance, bind NAT service boards to the NAT instance, and specify public address
pools.
# On Router A, create a NAT instance named nat1, bind the master and slave NAT service boards
to the NAT instance, set the master public address pool name to 1, set an address range from
90.1.1.1 to 90.1.1.10 for the master public address pool, set the slave public address pool name
to 2-bak, and set an address range from 96.1.1.1 to 96.1.1.10 for the backup public address pool.
