Dialer + virtual template + virtual access

[rthakker]

Guys I am bit confused and I want some help. I want to understand what’s difference between Dialer interface and virtual interface? In which scenario one should be using dialer interface or Virtual template? I also want to know when do u see Virtual-access interface and why?

In short I just want to understand fundamentals of all so if someone can tell me this else give me any web link where I can read else any book I can refer.

Thanks

Hi,

Multilink PPP uses the Virtual Access interface as a bundle interface to reassemble packets received over individual links and to fragment packets sent out over individual links.

• Dialer interfaces—Logical entities that use a per-destination dialer profile. Any number of dialer interfaces can be created in a router. All configuration settings specific to the destination go in the dialer interface configuration. Each dialer interface uses a dialer pool, which is a pool of physical interfaces (ISDN BRI and PRI, asynchronous-modem, and synchronous serial).
