Anthony, On the DC side,      maybe change the line permit tcp 10.5.1.0 0.0.0.255 10.6.1.0 0.0.0.255  (Allow all ports forward)      to be permit ip 10.5.1.0 0.0.0.255 10.6.1.0 0.0.0.255     (to be sure you don't miss anything)      and change the lines permit tcp 173.105.1.202 255.255.255.255 173.106.1.202 255.255.255.255 (EMC RP) permit tcp 173.105.1.204 255.255.255.255 173.106.1.204 255.255.255.255 (EMC RP)      to use the host key words, like you other lines. Makes it consistent and easier to read. permit tcp host 173.105.1.202 host 173.106.1.202 permit tcp host 173.105.1.204 host 173.106.1.204 ALSO, your "set ip next-hop" is the same IP on each location. You should set this on each side to be the next hop IP towards the other side. hth, Dan ... View more

Marian, Some older modules don't support setting half-duplex. Newer ones do. As an example older module that does not support setting half-duplex = WS-X6316-GE-TX. A newer module that does = WS-X6148A-GE-45AF Dan ... View more

Anthony, Not an expert. Here are (2) out of many links on Policy-Based Routing (PBR) from Cisco's site: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a008009481d.shtml http://www.cisco.com/en/US/customer/products/ps6599/products_white_paper09186a00800a4409.shtml Regarding your questions, 1. Should I do the PDR on the core switch or on all the routers? Our vendor suggests us to apply the same PDR on the routers (to routing the replication traffic based on ip and tcp port to the new circuit).    ->Yes, put PBR on both the core switch and on the routers at each site. You can create policies to route based on a number of different criteria. Reading through some of the above documentation might help you decide which is best. Your vendor's suggestion to use IP and TCP port could work fine. 2. Can PDR really do what we want that the replication traffic will not be redirected to others cirucits?    -> Yes, PBR will redirect the traffic as you specify. 3. Can PDR differentiate the data traffic and the replication traffic on the same server and route to the corresponding cirucits?    -> Yes, PBR would be able to "split" the traffic coming from the same server, with data traffic going to one circuit and replication traffic out to another. 4. If the new Metroethernet circuit goes down, the replication traffic will go to black hole, as the PBR next hop still shows up and PBR is still effective, but the path is actually down, is this true?    -> Not sure what your intention is here. You can configure PBR to route after a failure whichever way you need. You can route it to a black hole, or you can configure a default interface that you can use when the primary circuit is down. hth, Dan ... View more

Patrick, - do you have VTP running on the network? - are there any overlapping VLAN's between distribution sites? - what's the distance between distribution sites? Do you expect high latency? - what's the diameter of the switched network? Assuming no VTP, no overlap, small distance/low-latency between sites, relatively small # of hops between hosts that need to talk ... You can safely connect each of the distribution sites together for VLAN X. You should manually prune all VLAN's except VLAN X on the new distribution trunks. Use "switchport trunk allowed vlan X". hth, Dan ... View more
