Re: BGP

Hi
     I think Ravi we only update source when we r using loop back address
but I'm using physical address so in this case no need for update source
command. And as I mention above static route through R1 - R6 - SW1 is
working fine . But when remove static from there and create from R1 - R3 -
SW1 its not working . So when I look close to my configuration I found that
there is some routing configuration mistake in eigrp So I correct it but
still same result I also do Clear but no benefit .Ok let me try to explain
my topology I'm using IEW lab I verion 5

R6..Fas0/0.146>155.1.146.6 is connected with R1..Fas0/0>155.1.146.1.Then
R1..Ser1/0>155.1.13.1 is connected with R3..Ser1/3>155.1.13.3.Then
R3..E0/0>155.1.37.3 is connected with SW1..Fas1/3>155.1.37.7.And
SW1..Vlan67>155.1.67.7 is connected with R6...E0/1>155.1.67.6.
R6----R1----R3---SW1

So I experience today It is shows that you should do BGP relationship
through that path from which you r getting routes via IGP.

Any seggeations ......Please.

Thanks.
