Creating Authentication Accounts
You can create authentication accounts for other routers between the NAS and the HGW for VPDN.
On the NAS, an example is:
username NAS password cisco
username HGW password cisco
vpdn enable
vpdn outgoing cisco.com NAS ip X.X.X.X
On the HGW, an example is:
username NAS password cisco
username HGW password cisco
vpdn enable
vpdn incoming NAS HGW virtual-template 1
Using Continuity Test (COT)
The COT subsystem supports the Continuity Test (COT), which is required by the SS7 network to
conduct loopback and tone check testing on the path before a circuit is established. Continuity testing
(COT) will detect any failure of DS0 channels. It is required for North American SS7 compliance.
Note
You must have installed MICA 2.6.1.0 portware, which supports the COT feature.
Configure
There are no configuration tasks.
