Markus,
Kivas is right in that the use of the command
> R2 : dlsw icanreach mac-address 1111.222.3333 mask ffff.ffff.ffff
on R2 will eliminate explorers from being sent over the R1 <--> R2 (wan)
link.
The key here is understanding that when R1 and R2 form a connection they
will do a capabilities exchange
which is where R1 will be informed of R2's ability to reach the host listed
within the command. This would then allow R1 to answer any request (for
this host) from it's local reachability cache. This would therefore
eliminating the need to send explorer frames into the network
HTH
