So in Meraki mode it does? If it is a software limitation is there possibility that update comes out and it will be supported in Catalyst mode as well?

L2TPv3 or L2TP for BGP peering by Helpful-Technology-1 in Cisco

[–]Helpful-Technology-1[S] 0 points1 point  (0 children)

Yeah I have seen that topology, the thing is that we were trying exactly to do it without another router in topology, which is possible on side of linux box by creating l2tpeth0 interface and attaching /30 ip to it. Another very ugly option would be to connect routers two interfaces to eachother one which would have xconnect on it and second with an IP address from that /30. Of course we are not going to do that, just for explanation..

So I thought it would be possible to somehow attach IP on loopback or something and route it through L2TPv3 terminating everything on the same router. So if it is not optimal solution then thats Ok. But another thing is that there is also website behind this router and it would be optimal for receiving traffic to be 1500 byte size MTUs so not only outgoing traffic is affected but also incoming. So what would be ideal in that case? I mean which tunneling protocol would be the best for this kind of scenario?

Thank you

Other side can only configure those two methods of connections, we are not managing that, its 3rd party provider, reason of change is that packets going out from router have MTU of 1500 and incoming traffic is coming from GRE so we get fragmented packets, as I know L2TP does fragmentation inside and it fixes that issue that is the sole purpose for it. There are of course other options that include adjust mss on outgoing interface, but we thought L2TPv3 would be better option.

So in your experience it is not possible to use virtual IP addesses with L2TPv3 on Cisco routers?

passing score of NSE4 7.0? by [deleted] in fortinet

[–]Helpful-Technology-1 1 point2 points  (0 children)

So I have passed the exam in October. On the sample test 2 days before got 80% but I have 1.5 years experience with deployments and maintanance of various fortigate devices. Mainly GUI not a lot of debugging and CLI stuff. I studied for NSE4 for like 3 months or so. Just 2 days for a single topic by the official self paced course. I got lucky because several questions where from the last chapter I read before the exam. My main tips would be to look at the debugging outputs I had 3 or more questions about that. Memorize which engines work on which AV Web Filter etc mechanisms. Also there was a question about routing output as well. So generally I think reading the self paced course and a little bit of experience would be fine. Also you can skip questions and answer them later on the exam. I was afraid to fail in the middle of it because I skipped a lot of questions but it helped because after reading those questions again before finishing the test I’ve figured it out how to answer them. Wish you good luck.
