I have what appears on one level to be a basic question. I was tasked with coming up with a plan to support 2 remote sites that don’t have IT people. Each site has an ISR4400 series and a 9200 switch stack with 2 switches. There is a spare 4400 and a...
This might be a dumb question but I just noticed something with a gre tunnelBrought up a new gre tunnel src 10.0.1.1 dst 10.0.1.2tunnels stable I can ping the dst address from the source on both sides. Why can’t I ssh to those addresses across the t...
I have a remote site I need to make some tunneling changes to. It connects back to the core router by way of a layer 3 circuit to another remote location that has a dedicated p2p to the core. R1<>L3circuit<>R2<>leasedline<>R3coreR1-R2have a gre tunne...
I’m just making sure on this. If you have two GRE tunnels whose source is the same interface, both MTU would still be 1476 correct?For instanceInterface gig 1/0/1ip addr 192.168.1.1 255.255.255.252tunnel 1ip mtu 1476ip tcp adjust-mss 1436tunnel sourc...
I have router a with a gre tunnel (tunn 1)to router b. Gig 0/0/0 to Gig 0/0/0i need to make another tunnel from A to a third on router C. C is connected to B on gig 0/0/1. No routing protocols it’s a small network all static’s. What’s the best way to...
Just came across this even though it’s old Ive got some info, as it appears this command is not part of the command reference but is specific to the asic. There is surprisingly little documentation.First Google Gemini can analyze it as well and tell...
TCP windowing is the first thing that comes to mind. However what I’m also curious to know is what the OS is on the two hosts at each end as that from previous experiences can have a huge impact on just such a scenario.
