Re: Admin Distance of External EIRGP route

Le,

It is always risky to claim that the IOS CANNOT do something, without knowing
the source code, but, that said, there is no way I am aware of to change the
AD for particular external EIGRP prefixes. This question has come up before on
the list, and others have come to the same conclusion. If the task allows,
change the AD for all external prefixes with the "distance eigrp" command.

HTH,

  Subject: Admin Distance of External EIRGP route

  Hi group,
  Is it possible to change the Administrative Distance (AD) of a specific
EIGRP
  external route ?
  Take the following for example:
  R1f0/0---------f0/0 R2----loop1
                             |
                          loop2
  R1 and R2 run EIGRP on ethernet segment, R2 redistribute loop1 and loop2
into
  EIGRP. R1 wants to change the AD of route to loop1 to 190 and keep the AD
of
  root to loop2 (AD=170).
  The "distance 190 IP_add_of_R2_f0/0 Access-list" does not help. This
command
  only can change AD of internal EIGRP routes.
  The "distance eirgp 90 190" changes AD of all external EIRGP routes.

  Can anyone help ?
  TIA
  le
