RIP: R6 shows "bad source" in debugs for BVI interface on BB1

Hi,

 

I turned the rip debug on R6 and I noticed that RIP is complaining about "bad source" from 54.1.10.254:

*Jul 26 07:06:56.848: RIP: ignored v2 update from bad source 54.1.10.254 on Serial0/1/0
*Jul 26 07:06:57.756: RIP: received v2 update from 54.1.1.254 on Serial0/1/0
*Jul 26 07:06:57.756: RIP: Update contains 4 routes

[Serial0/1/0] in my setup is connected to BB1

 

on BB1, the BVI interface has this IP address:

BVI1                       54.1.10.254     YES manual up                    up

I haven't done any exercise in the RIP workbook related to this case but just wondering...is this expected? is it there for some exercise we plan to do in the future or is there an error in my setup?

 

thx

    I think I may not what the issue is. I haven't changed the IOS version
    from Voice to Adv IP services on my 2801. Do you think that's the
    reason? My config below:
