Good morning, I'm new in Cisco forum; I need to ask about the ISL on cisco router: I would to buy a R 2610 (used) to build my lab to study for CCNA certification. I sow the answer of Inzeos781 in this forum posted Jul 4, 2007 where to configure the ISL is needed minumum 2610 with max memory and image c2600-is5-mz.12.3-22.bin and feature set IP Plus+ IOS later than 12.2T.
This is the version that I would to Buy: IOS (tm) C2600 Software (C2600-I-M), Version 12.3(22), RELEASE SOFTWARE (fc2), System image file is "flash:c2600-i-mz.123-22.bin", (not c2600-is5-mz.12.3-22.bin as Inzeos781 wrote)
1 Ethernet/IEEE 802.3 interface(s)
2 Serial(sync/async) network interface(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
Question: can I configure the Vlan ISL on this router in an ethernet 10 mbit and not fast ethernet, without maximum memory, only to study? If somebody or Inzeos781 could answer me I will grateful. Thank You in advance.
The ethernet port on 2610 doesn't support isl encapsulation no matter what ios image has been installed, however, it can supports dot1q encapsulation if proper ios image has been installed. To support isl encapsulation, you at least need one fastEthernet port. You can do this either by installing one NM-1FE-TX to the NM-slot of the 2610, or just buying one 2620 router which has one built-in fastEthernet port.
