Re: Forwarding UDP broadcast over GRE Tunnel. [7:64647]
hi i see no reasons why it can't be done. u could use the following in int config mode: ip helper-address x.x.x.x use the brodcast address of the network that should receive the udp traffic (directed broadcast). specify the udp port that the application uses, by the following in global config mode: ip forward-protocol udp x Regards, Amar.

Re: Unexpected behavior of IGRP and EIGRP [7:64625]
Hi, actually it is Eigrp that has a better AD than Igrp, 90 and 100, respectively, the route u see in ur table has 170 as the AD, therefore External EIGRP,caused by the implicit redistribution, imposed when using these routing protocols with the same AS. so u are having normal behavior of the protocols. but i can't figure out why u r using IGRP in R3, since obviously he would know about the routes.

Re: network design [7:64422]
i guess that the best way to get around how many hosts can be put in a giving broadcast domain will depend very much on the traffic patterns and the load the users put on the network add to that the diffrent applications behaviors as well as the windows behavior, so i think there is no right answer here, it all depends on the environment. as a rule cisco recomands, no more thatn 500 IIP users per broadcast domain, but then again the above must be drilled, if there is other desktop protocols that rely heavely on broadcasting, it is another story. the big question is not how much of these host i could get away with putting in one domain, but how scalable will the environment be in regards to the companys direction, simply u don't wana redo the hall thing when ur client wants to deploy a new technologie, or more application or what have u, more or less adaptability and scalability and relibility in face of the coming environment should be weighted out agianst how many host a person could get away with puting in a braodcast domain.

Re: How do you change tcp port for telnet on a router? [7:64857]
the un-encrypted password, well, obviously. telnet x.x.x.x 3001 will hit one of the available terminal lines on rotary group 1, when u run it from a cisco router, other wise, from an os point of view the argument would be the port number that the telnet service listens on. the question was, if the telnet service can sit on a port other than 23, in a cisco router or switch for that matter. i have not a found a way to do it(but, i haev not looked ver hard, either), but it can be done by nating the tcp port of a giving ip, efectively arriving at the desired solution. u could use " ip alias" command to bind an ip to a giving line, or port, much like what happens automatically with async links.

Re: Load Balancing and NAT [7:64904]
could u give us more info pls, as far as the IP's that you will be using. wasn't it u that wanted to assign 2 ip's for each server you have? if that is so,u can do the following: creat 2 VLAN's on ur switch. creat 2 subinterfaces on the router(must have fast ether) for the vlans. PBR every thing from ISP A to VLAN A, both ways. PBR every thing from ISP B to VLAN B, both ways. make sure the servers don't symetrically route the packets. with the above, u will have control over traffic that crosses ur router, but then which IP will the clients use, depends on the DNS config, wether it will load balance on DNS queries is also another issue, so more or less u will have no control over traffic coming to ur network. if you had ur own net block, it would be easy to load balance, u'd have to call ur ISP's they will give u a community that u will joing from which they will load balance, but you will need BGP, of courrse. but please give more information to further think it out.

Re: Load Balancing and NAT [7:64904]
that will work. every thing going out will overloaded. and an inverse NAT is done for the packets coming in. u will have controll over the traffic getting out, that is on a round robin fashion, one packet out se0 the next out se1. the traffic coming in the links will depend on the IP's u use on the NAT statements(the static ones)thereby giving some sort of control, if you see a link being over utilized, u could use more IP's from the other POOL giving by the seconf ISP, to balance it some what.

Re: Frame Relay Design/Bandwidth Question [7:65401]
hi ching, first i must say, that an LL, is most cost effective when the locations ur connecing are close in proxemity. FR will cost you less if the location if far away. for the location that has bursty traffic, you can either get a 0cir link, which doe't cost alot, but the amount of traffic should be meassured before of course, and the SLA from the provider should be checked. finally you can always get an ISDN or simply an async connection configured with DDR.

Re: Spanning tree question on .1q trunks [7:65386]
ur right about the frames ability to use gig0/2 only if the gig0/1 goes down, but according to the standard, the link from which bpdu's arrive with a higher cost will be put on blocking, but visibely that is not the case. some one will surelly respond to this.
