RE: T1 [7:14397]
Never heard of one. Who is the Service Provider for the T1 in question?

RE: The Proxy ARP process [7:12198]
What it is: Proxy ARP is a method by which routers make themselves available to hosts that do not have a configured default gateway. Proxy ARP is enabled on Cisco routers by default. no ip proxy arp is the command to disable Proxy Arp on a per interface basis. Consider the following: Host A (192.168.1.2/24) needs to send a packet to host B (192.168.2.2/24) located in another network. A router with two ethernet ports connects to the 192.168.1.0 network on its first Ethernet port, and connects to the 192.168.2.0 network on its second Ethernet port. 192.168.1.0 192.168.2.0 Network Network Host A---Router--Host B .2.1.1 .2 Host A does not have a configured default gateway, and therefore does not know how to reach a router to connect to hosts outside the 192.168.1.0 network. Consequently, it may issue an APR request for 192.168.2.2. The router, receiving this request on Ethernet 1 (with Proxy ARP enabled), and knowing how to reach network 192.168.2.0, will issue an ARP Reply with its own MAC address in the hardware address field of the ARP Reply. In doing so, Host A believes that the router's Ethernet1 interface is the interface of Host B. Host A will make an entry in its ARP table using the MAC address of Ethernet1 on the router for Host B and unicast all subsequent packets for Host B to the router. See RFCs 925, and 1027. Are you having specific trouble with something?

RE: VLAN on 1750 router [7:12024]
Mamoor, To my knowledge, the only 1700 series router that supports IEEE 802.1Q VLAN is the 1751. The fast ethernet interface may require the encapsulation dot1q command, rather than the encapsulation isl command.

RE: Help with Inter-Vlan routing on a Cat 5??? [7:11966]
You may want to verify the version of RIP that you're running on all routers.

RE: Cable connection from a 2502--- Andrew mau?? [7:11961]
Transmit pairs are 3 and 6, and Receive are 4 and 5 for Token Ring RJ45 interfaces. Fabricate a patch cable pinned out to the 568-B wiring standard on one end, and change the other end to cross transmit an receive pairs. End A Pin 1 OrangeWhite Pin 2 Orange Pin 3 GreenWhite Pin 4 Blue Pin 5 BlueWhite Pin 6 Green Pin 7 BrownWhite Pin 8 Brown End B Pin 1 OrangeWhite Pin 2 Orange Pin 3 BlueWhite Pin 4 Green Pin 5 GreenWhite Pin 6 Blue Pin 7 BrownWhite Pin 8 Brown That would provide a crossover patch cable for token ring to directly connect two token ring devices. Another approach, if you're interested, is to fabricate a loopback plug. Use the same concept, but apply it to a single RJ45 plug. What you should end up with is a plug that has one wire connecting pin 3 to pin 5, and pin 4 to pin 6. See if that will put your interface in to looped mode when you do a show interface. Hope this helps.

RE: Media Converter [7:11903]
When you say you have a 256k channelized E1, what do you mean? Is it a fractional point-to-point circuit? What encapsulation method are you using for layer 2? Could you elaborate on the application?
