Configuring IPv6 DNS 229
Configuring IPv6 DNS
Configuring Static IPv6
DNS
You can establish the mapping between host name and IPv6 address through the
following configuration. When applying such applications as Telnet, you can
directly use a host name and the system will resolve the host name into an IPv6
address. Each host name can correspond to only one IPv6 address.
Follow these steps to configure a host name and the corresponding IPv6 address:
Configuring Dynamic
IPv6 DNS
If you want to use the dynamic domain name function, you can use the following
command to enable the dynamic domain name resolution function. In addition,
you should configure a DNS server so that a query request message can be sent to
the correct server for resolution. The system can support at most six DNS servers.
You can configure a DNS suffix so that you only need to enter some fields of a
domain name and the system can automatically add the preset suffix for address
resolution. The system can support at most 10 DNS suffixes.
Follow these steps to configure dynamic IPv6 DNS:
Configure the capacity and
update period of the token
bucket
ipv6 icmp-error { bucket
bucket-size | ratelimit interval
} *
Optional
By default, the capacity of a
token bucket is 10 and the
update period is 100
milliseconds. That is, at most
10 IPv6 ICMP error packets
can be sent within these 100
milliseconds.
The update period "0"
indicates that the number of
ICMPv6 error packets sent is
not restricted.
