We are opening a new office that is roughly 20km from another core site. We plan on provisioning 2 x DS3 between sites and likely have a requirement to support the same subnets (VLANs) at both locations. Let?s say we have our core site (SA1) and new site (SA2). Core infra will be at SA1 (WAN, Inet, Servers, etc).
SA1 has 2 x 6513?s running HSRP and VTP load balancing ? core of the LAN. Has anyone spanned VLAN?s across sites like this and know of any major concerns to watch out for in doing so? One concern is delays from L3 lookups to the remote MSFC?s ? MLS should help here for any cached routes/decisions.
