Subnet mask/ OSPF Routing [1:3308] posted 04/15/2001
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


Can ping one way with response from host B to A but not from host A to B.  I
can ping host B just fine from everywhere but host A.  In Cisco's CIT book I
remember the exact situation which resulted in a subnet masking error but
everything seems to be fine as far as I can see.   advice would be appreciated

Thanks,
