Hi, I have a question: if i want to set up GRE tunnels between 30 sites, what kind of router should i use? site1 --Internet -site2 | . site3 ..

Will each tunnel be on a seperate physical interface? how many physical interfaces do you need? what interface types? What is going over these tunnels? How much utilization do you expect the GRE's to have?

Re: How much GRE tunnel can supported on Cisco routers
We also need to know what processord you will use the 100 , 200 or 300. What interfaces. The problem lies on the processing power needed to do this. If you split the GRE on multiple Interfaces all running CEF there will be less load on the processor and therefore more tunnels will you be able to have. What else will you be running on this box ACL's and other commands utilize alot of processor. What type of cost are you looking at also do you want a 7200 or is the 3600 the max you are willing to pay for a router?

RE: How much GRE tunnel can supported on Cisco routers
OK, more detail, We need 30 tunnels on a single phisical interface, this interface maybe serial port which connect to Internet. I hope all these tunnels begin at the serial interface of site1 router, and end at others serail interface which connect to Internet too. The GRE traffic is not too much, about 10% of the total traffic on the interface, other 90% traffic is normal Internet traffic. The main purpose is to allow the users in site1 to access Intranet servers in other sites. -Original Message- From: Brian [mailto:[EMAIL PROTECTED]] Sent: Wednesday, November 22, 2000 2:54 PM To: Liu Jianxin-qch1927 Cc: [EMAIL PROTECTED] Subject: Re: How much GRE tunnel can supported on Cisco routers On Wed, 22 Nov 2000, Liu Jianxin-qch1927 wrote: > > Hi, > > I have a question: > > if i want to set up GRE tunnels between 30 sites, what kind of router should i use? > We need more info.
