I have read various documents recommending that flooding be enabled to mimic legacy network behavior but i was looking for specific guidance for what scenarios traffic will not reliably work if flooding is disabled under the BD. My intent was to ide...
Fellow Engineers,I was recently reading a cisco documentation discussing solutions to minimize/avoid fragmentation issues with ipsec and gre and was hoping just to get some further clarification. My understanding is that there are 3 major solutions ...
Fellow Engineers,I've got a conceptual question that I've been wrestling with due to a customer inquiry....I recently had a customer inquiry that stated that he was getting roughly only 1.5 mb transfer speeds over his 2 T-1's to the internet. Exclud...
Fellow engineers,I did a lab scenario utilizing bgp router refectors and and ran into a problem in which the router reflector would not reflect routes until I disabled sychronization. Could someone further explain the mechanics behind this.It doesn'...
Fellow Engineers,I have a customer that is setting up a 3com ip phone (NBX) system that uses multicasting for some of its functions. Whats causing me trouble is that the customer has a layer-3 switch directly behind our router that is non-cisco and...
Thanks for the clarification. Nothing specific from a document perspective, I was just referring to PPT decks that reference enabling flooding for integration with legacy networks as a general recommendation. I currently have an L2 based network th...
I would just consider converting your architecture over to 2547oDMVPN with IPsec. If you are going to build the hub and spoke tunnel overlay anyway then it will be much cleaner from a architecture perspective to use the native DMVPN encryption capab...
Sprint supports EIGRP on their Global L3VPN product. Cisco's BGP cost community implementation with EIGRP works pretty well in terms of minimizing routing loops but convergence/transient loop conditions can still be an issue without appropriate filt...
Have looked into what Cisco calls a half-duplex VRF?It removes the critical requirement for a separate VRF per customer but I'm not sure the solution meets all of your needs.-Greg
To get this to work on the ASA you need to set the pre-shared key on the L2L base group which does not require a peer address. This behavior resembles what you would have had to do on a VPN concentrator. To see the base group:show run all
