Switch between dialer interfaces/configs in a router ?

Question

I have an 871W router with a separate ADSL modem.

It has a FA 1 as a trunk to the LAN (which operates in vlan 10) VLAN 10 declaring itself as part of bridge-group 10 BVI 10 with the IP address of the router "Dialer 1" interface with dialer pool 1 FA 4 interface with dial pool number 1

The dialer 1 interface has the PPPoE credentials.

My ISP is deploying MLPPP (in test/beta mode with bugs). I would be using a single link MLPPP. (this bypasses the telco's throttling equipment since the IP packet is offset by a couple of bytes)

Is it possible to have a "test" dialer interface with different credentials and the ppp multilink commands to get MLPPP, and quickly/easily switch from the "production" PPPoE dialer to the test MLPPP Dialer configs ?

There are routing and IP NAT entries which specify "Dialer 1", so creating Dialer 2 with the new config might work to establish the link, but wouldn't work for NAT/routing.

Is the only way to write some script that will "manually" modify the dialer 1 interface from one config to the next ?

Is there a command that will completely zap "Dialer 1" so I can re-enter a config without fear of leftovers from the previous one, or must I negate every command that setup the previous config before entering the new config ?

Thanks !Will the "no int fa 4" also work for a "real" ethernet interface ?(reset the interface to default config). or does the No Interface workonly for virtual ones ?

I think that does not really work.  When you create it again, someold config may come back.  Can be avoided by saving the config andreloading the router first.

Greetings,You cannot remove a REAL interface (unless it is a piece of H/W that can be removed), only a VIRTUAL interface, However you CAN set an interface back to its default values with -	default int fa4Cheers...............pk.

I have not noticed that, but then I have rarely removed a dialer, probably only because I preferred 0 over 1, or is it the other way round?

I do recall reading about weird magically restoring confg somewhere but I can't recall any details - at all.
