Task 11.2 AS path filter

Task 11.2

The given solution is:
ip as-path access-list 1 permit _54$

Sounds strange to me.
With this filter, a prefix sourced by R6 (for example by a network command) couldn't be annouced to R2. This behavour is not required by the task.

I would use instead this configuration:
ip as-path access-list 1 permit ^$
ip as-path access-list 1 permit ^54$

imho
