IP Routing Table issue

Hi all,

 

yesterday I stumbled upon a strange situation on a net-net 3820 box:

 

 

SBC1# sh routes

0.0.0.0/0          1.1.73.44  2010003  2      268         1   0 sp0
...

...
6.70.6.64/26   1.1.77.20   2010003  1      25          1   0 eth0
6.70.6.76      1.1.73.44  2020007  1      9904        2   0 sp0

1.) am now wondering why a single host IP points to a different GW instead of using the GW of IP subnet:

 

host-routes
        dest-network                   6.70.6.64
        netmask                        255.255.255.192
        gateway                        1.1.77.20
        description

 

2.) Probably am missing the obvious, but do anyone know a way to remove a single IP route table entry?

 

 

Cheers!
