• The DNS IP address(es) are determined by the
set tunnel-pmip advanced
dns
command.
Use the
set tunnel-pmip advanced dns1
command to define the DNS server IP
addresses to be provided to the client by the AP through DHCP in case the AP
can not obtain corresponding settings from the HA. The optional
dns2
parameter specifies the backup DNS server in case the primary one is
unreachable.
Mapping User Traffic
/protocol/te-<eng>/map vlan {untagged|<VLAN ID>} to <index>
[domain <string>]
/protocol/te-<eng>/unmap vlan {all|untagged|<VLAN ID>}
The
map vlan
command instructs the tunnel engine to forward traffic to the
specified tunnel. You can specify either traffic associated with a specific VLAN
or traffic that is not tagged for any VLAN. All packets that meet this criteria
received by any of the node’s radios are forwarded through the tunnel. If the
tunnel is not configured or not active, all corresponding packets are dropped.
If you specify untagged traffic, then the tunnel interface itself must be associated
with a VLAN. Refer to
“Setting Tunnel Engine Parameters” on page 167
.
The optional
domain
parameter is for PMIP tunnels. Some PMIP
implementations require an additional identification string to communicate with
the PMIP Home Agent (HA). The
domain
parameter allows you to specify the
required string.
The
unmap vlan
command removes all tunnel mapping entries or a specified
tunnel mapping entry. After this command, the specified packets are then
forwarded as if the tunnel does not exist.
Configuring
Authentication
/protocol/te-<eng>/set tunnel <index (1-5)>
[secret <shared_secret>]
[ppp-name <id>] [ppp-password <pw>]
[backup-secret <backup_shared_secret>]
[backup-ppp-name <backup_id>] [backup-ppp-password <backup_pw>]
/protocol/te-<eng>/set tunnel <index (1-5)>
authentication {enabled|disabled}
The
set secret
command configures the parameters for L2TP authentication for
a specified tunnel. The
secret
parameter sets the shared secret for tunnel
authentication. The
ppp-name
and
ppp-password
parameters set the data for
session authentication. The settings for each of these three parameters must
match the equivalent settings on the main router.
The
backup-secret
,
backup-ppp-name
and
backup-ppp-password
parameters
are equivalent settings for a backup router.
