Re: Have a Linksys WRT54GL? WRT54G3G? or WRT310N?

I don't think this is the same... I saw this today. Linksys work!

Re: Hands up those who find a 'belkin' works better @ home

Simple comparison: say you have a domain name against your public IP. How this works in ASA: configure DNS doctoring so the ASA rewrites the DNS reply public IP with the private IP How this works in IOS: NAT virtual interface (dog slow performance). It just doesn't work if you use traditional ip na...

Re: How in depth is CCIE multicast + old textbooks + SSM con

MOSPF isn't even supported by Cisco gear so you really don't have to worry about that one ;) Also not mentioned yet is Bidir PIM and MSDP, both of which are totally fair game. You'll also need to go over the supporting protocols like IGMPv2/3 and MLD. I'd stop at MDT though. That's not likely to be ...

Re: What experts think about this network?

If someone I was interviewing tried to give me something like this I would likely not look at it.The problem with things like this is you have no way to prove you actually set it up, and even if you did there's no way to prove you did it from knowledge in your own head. The only way to tell that you...

Re: Pass Broadcast between interfaces on 2911 Router

Sorry, I only have my CCNA, and am still learning. So you say if my interface has 192.168.1.1/24 as ip address I can also assign the same interface 192.168.20.1/22, and the interface will talk to both networks? Would I still create an ospf/eigrp route to tie the two networks together sort of like r...

Re: Pass Broadcast between interfaces on 2911 Router

Wait. We're just talking about client workstations on this subnet? Oh man, you're making this way harder than it needs to be. Create the new DHCP scope on your server. Then on the old scope reduce the lease time down to 5 minutes. Once all the clients renew their leases and have the new lease time f...

Re: Pass Broadcast between interfaces on 2911 Router

I get that you want to use a new interface. I'm telling you that you don't have to. You can create a mulitinet on the existing interface.

Re: Pass Broadcast between interfaces on 2911 Router

Just add the new IP as a secondary on the same interface.

However, this will technically work for the 255.255.255.255 broadcast address, but directed broadcast addresses will still be dropped by clients in the opposing subnet.

Re: Web content filtering

I have a Barracuda Web Filter deployed with one customer. It works well enough. Had a few weird issues with it that were support calls.

I don't think an ASA can do PPPoE, can it? That might make your choice for you.

So use IPsec tunnels instead. Or IPinIP. Or tunnel GRE inside of GRE.

Needs a purpose. It's all nice and everything to bring up BGP peerings but then what? What do you do with it? It's gets boring fast and people lose interest.

Re: IGMP snooping behaviour

Yup, that's exactly right. 224.0.0.0/24 is the link-local multicast range and must always be forwarded.

Re: IGMP snooping behaviour

Likely because of one of the first three forwarding rules of IGMP snooping. http://tools.ietf.org/html/rfc4541 2.1.2. Data Forwarding Rules 1) Packets with a destination IP address outside 224.0.0.X which are not IGMP should be forwarded according to group-based port membership tables and must also ...
