Multiple DS3 Private Line - Interleaving/LB options?
Due to the fact that we have a LEC time interval issue with procuring an optical long-haul Ethernet circuit between our 2 datacenter locations (one in TX and one in AL), we have been forced to migrate to ordering (3) Private Line DS3 circuits.
Equipment: 6513s on each side currently supporting dual-MPLS providers & redistributed routing tables for each.
These circuits will be used for replication of data between our 2 datacenter facilities.
Do we have any options with interleaving the traffic across all 3 of these circuits outside of having any L3 functionality or protocol-based load balancing? (I don't know of anything outside of multipath/multihop/CEF which are not applicable here)
On our existing P2P L2 circuits, we currently have to use manual routing via static route statements and use IP SLA to monitor each side of the links to assist with failover.
Would it be a good design if we had dual 7204VX routers on the inside of ther 6513s that could isolate these links from the remainder of the core IP/MPLS network and we could then have more options with multilinking of these circuits? (IP CEF with per destination load balancing?)
Re: Multiple DS3 Private Line - Interleaving/LB options?
Will the data replication be seen as one src/dest flow or multiple src/dest flows? If the former CEF per-destination might only use one path. CEF per-packet load balancing would much better utilize the 3 links but exposes you to flow sequencing issues. Unknown how well, or whether, 6500 or 7200 might support something like MLPPP for 3 DS3s.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
