Hi All
I'm doing the Internetnetwork experts R&S Adv. Technology v4 - Router on a
stick and Native VLAN lab (page 12). I know configuration is correct but I
can't seem to ping 16.0.0.6 <http://16.0.0.6/> from R1 (16.0.0.1
<http://16.0.0.1/> ).
When I do a debug ip packet on R1 I get the following:
*Mar 1 00:11: 31.353: IP: s=16.0.0.1 <http://16.0.0.1/> (local),
d=16.0.0.6 <http://16.0.0.6/> (Ethernet0/0), len
100, encapsulation failed.
Doing a debug arp on R4 I get:
*Mar 1 00:11:31.927: IP ARP req filtered src 16.0.0.1 <http://16.0.0.1/>
0004.c05f.9e00, dst
16.0.0.6 <http://16.0.0.6/> 0000.0000.0000 wrong cable, interface
Ethernet0/0.
I'm running the following devices:
R1 = 2611
R4 = 3620
Any suggestions in what can be causing the problem?
Thanks. EP
