Hi all, i've faced a problem of 802.1Q trunk between Catalyst 4003 & 3640 router. This is what i've configured : For 4003, i've enabled the trunk to use 802.1Q encapsulation, plus allow the necessary vlan ID being carry over the trunk. For 3640, i've configured the subinterfaces for each of the vlan ID, plus the 802.1Q encapsulation. The 4003 switch was using VLAN1 ip address, but the 4003 switch couldn't ping to the subinterface ip address of VLAN1 of 3640 router, vice-versa. I have configured something similar to this before, but i use ISL instead of 802.1Q. Hope anyone out there have face this problem before, also have solution to solve this issue. Thanks in advance. regards, lee ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
