Hi all,
I schould redisign a given network. it is a medium enterprise net with
2 cat6509 (core) and 4 cat6509 as distribution.the customer also want to migrate to a full L3 network. actual there are only L2 EC between the routers. right now, what is the best design or what is a good way top make decission ?? first I like to change the L2 trunk between the core's to a L3 trunk. then there is a redundant connection between the core's and all distribution routers.these should also a L3 trunk!! should i need also the trunk( actual L2) between both destribution routers ? if yes, L3 or L2 ? for me to understand it's not important ?!?! but in some case studies I saw there is a link not only to the core's also a link (EC L2 or L3) between the distribution routers ?!?!distri1--------------------------------------L2 EC trunk---------------------distri2 | also cross connection distri1/2-core1/2 | | | | | core1--------------------------------L2 EC trunk--------------------------core2 | | | also cross connection distri1/2-core | | | | | distri3--------------------------------------L2 EC trunk---------------------distri4
