Hi, I have 2 pc's connected to a Cat5 switch on ports 2/1 and 2/2. The ip's are 10.1.1.10 and 20.1.1.20. Their default gateway points to 10.1.1.100 and 20.1.1.100 respectively. Trunking in enabled on these ports. A 2620 router with subifs. at 10.1.1.100 and 20.1.1.100 is connected to port 2/12. Subif f0/0.1 is enabled for isl 1 and f0/0.2 is enabled for isl 2. Trunking is enabled on port 2/12 also. The Cat5 has a vtp domain of CISCO set. Also a vlan is created using: (enable)set vlan 20 name test2 The default vlan Vlan1 I guess is for pc1?? The sc0 int. is set for 10.1.1.5 and ip route default to 10.1.1.100. A Ping from 10.1.1.10 to 20.1.1.20 is NOT working! Can anyone advise a checklist or a missing config. regarding this. Thanks! _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=10580&t=10580 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
