Let me set the record straight. My only goal here is to prepare and succeed in passing the Cisco CCIE written and lab exams. I know that there are features and options that are available in certain versions of IOS, and those options can be, and are likely un-useful, to CCIE candidates. However, it should be the focus of this group to understand and comprehend the specific feature available in the IOS releases that are used in the written and lab exams. It makes no sense, and in a certain view is detrimental, to bring up features that are only available in versions of IOS that will not be used in the testing criteria.
If there have been any features that are available in the exams that I incorrectly misrepresented, then please correct me. I will be taking the written and lab exams in the near future, and would definitely benefit from the feedback of this group. I don't think it is useful to inject features that are available in IOS versions that will not be used in the testing into this discussion. Again, correct me if I'm wrong. I'm new to this group, so this may be out of line...

[7:72738] 12.2(15)T5 is a recommended version for the IP v4 exploit, as far as I know, see (http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml). Are you suggesting that it is not appropriate? Do you recommend that we configure an "unreleased and unsupported feature?" I would not recommend that in a CCIE lab, as they are historically behind in IOS releases, and will not likely support a configuration in a 12.3 version specific command, as a valid solution since they are not even going to support 12.2 until this Fall...

[7:72738] Uhm, Why don't you just put the command there and see what's going on. I don't mess with 12.2.15Tx any more since, FYI, it has a bug with EIGRP stub connected - forgot the bugID, but if you have a spoke with that command, the hub won't withdraw routes even if the hub doesn't have that route any longer. Okay, to the main topic - I run 12.3.1 on a 7206VXR and I could configure bridge-group on the tunnel interface. interface Tunnel10 bandwidth 1500 ip unnumbered Loopback1 ip mtu 1440 ip hello-interval eigrp 2002 10 ip hold-time eigrp 2002 40 keepalive 10 4 tunnel source 172.16.1.140 tunnel destination 172.16.3.144 bridge-group 1 bridge-group 1 spanning-disabled But it does say this :" CS140(config-if)#bridge-group 1 % This command is an unreleased and unsupported feature -luan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Reimer, Fred Sent: Tuesday, July 22, 2003 5:48 PM To: [EMAIL PROTECTED] Subject: RE: GRE TUNNEL/Ethernet-broadcast-like? [7:72738] Wow, I hope you don't try that on your CCIE lab! Last I heard, bridging was not supported on tunnel interfaces. At least it's not on the 12.2(15)T5 running on a 2651XM router I just tested. If you find a (recent, supported) version of IOS that supports "bridge-group" in a tunnel interface please let me know. I think proxy ARP is more what is needed here, if we are talking about IP traffic. If not, then IOS should support the other protocol in the tunnel (it supports AppleTalk, Banyan VINES,CLNS, DECnet, IP, or IPX). If it's "raw" NetBIOS or SNA, then setup DLSW peers...

[7:72738] Uhm. Never done this or heard of this before. I would just do something like: Interface LAN 1 Bridge-group 1 Interface tunnel 1 Source WAN Destination REMOTE_WAN Bridge-group 1 Since, concurrent routing and bridging makes it possible to both route and bridge a specific protocol on separate interfaces within a router, then WAN just route and LAN/Tunnel just bridge :) If that not work for you, then maybe try intergrated routing and bridging - create a BVI and source the tunnel from that interface. -luan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 22, 2003 1:34 PM To: [EMAIL PROTECTED] Subject: GRE TUNNEL/Ethernet-broadcast-like? [7:72738] Hello, A question barely came up to mind: Would it be possible to "join" a broadcast domain, not by means of a LAN switch but from one remote router to another, using GRE Tunnels? Since I haven't done it before, I kind of thought that it'll be possible. For instance, having: R1eth0(no ip address)--GRE TUNNEL-Ser0--CLOUD--GRE_TUNN--Ser1---R2eth0(no ip address) , where arp packets may flow from R1 to R2 via this GRE Tunnel. Under this scenario and simply put, can R1'sLAN be also part of R2'sLAN? If it's possible, how could the config be like?
