Routing loops with ibgp and ospf running Backbones
Hi ! I have the following network setup running ospf, ibgp within the Domain and ebgp beween AS. GW: Gateway router BB: Backbone Router Note: BB and GW router is connected directly (cross-connect) and the Area0 is extended from BB to GW router. Pre-requisite: LAN on Area 11 shud able to access both the routers for redundancy. Implementation : Implemented HSRP between BB and GW and extended the Area 0 using cross ethernet back to back cable between BB and GW. Route-reflectors are confgured on IBGP routers and EBGP on GW routers. Both the GW routers are connected to the same ISP. Preoblem : sometimes I am getting routing loop between BB and GW routers when trying from Area 11 LAN( default Gateway for all the machines is GW). Action taken: Checked the ip route and gound that the defualt gateway on GW is pointing to Internet interface and for BB it is pointing to GW. The looping occured between the back to back connected interface. Can any body suggests the way to troubleshoot the problem _ Chat with your friends as soon as they come online.

Traffic Shaping and Access control
Hi ! I have the following scenario -- R2 LAN2 LAN1---R1 -- R3 - LAN3 Note: R1 is the end customer R2 is ISP1 edge router R3 is ISP2 edge router DEFAULT IP ROUTE IS POINTING TO BOTH R2 AND R3. (MUST) Any traffic comes from LAN1 with www request to go on R3 and rest of the traffic shud be routed via R2 only. How do I limit this acess..

Re: Re: IP Tunneling - Typical requirement
The customer is running the Checkpoint firewall which is registered with IP address of the other ISP ( the existing one). Now they are going to take a DS0 connection from our network. For them to change the IP or add IPs at firewall they require to minimun of 30 days.Meanwhile, they want to use both the lease lines from us and from the other ISP. The customers total network and Servers are behind the firewall. Hence they have the only exit pont from firewall which inturn pointing to the ethernet interface ( configured with the other ISPs) as the firewall Gateway. Now, if they take my link with another serial port then how do i serve their LAN (inside the checkpoint FW). They want to go in only with this firewall.Security between the links is not of concern. - xyz ISP LAN FW --- Router - my ISP The FW/dns /web server r configured with the xyz network and they need min. 30 days to change the ips to my ISP.But they want to use the services to both meantime. How do I accomplish this. What I thought is like this. 1. Ask the xyz to allow the adv of their part of the network with us. ( This is ruled out as they are not accepting) 2. Create a tunnel of IP over IP on the my ISP serail inface. Convert the other IPs request into my ISP IPs and route their request via my network, How can I do this with out using any additional SW ( ie only using cisco routers ).

Many companies that are doing business via the internet use IPSEC to create secure encrypted access into their intranets or extranets. If you not concerned about security of clear text traffic between your companie and your partners then just simply open up your router/firewall to permit this connection. --- A Mateen [EMAIL PROTECTED] wrote: Hi !
