Re: SQL Satellite links VPN/GRE

as in an earlier post i would check the mtu sizes (GRE and IPSec adds alot of overhead). Your traffic may route fine with smaller data transfers, but crap act up with heavy data. are the SQL servers replicating at all?

Re: SQL Satellite links VPN/GRE

D-Garnett,

MTU was the original problem. We set the MTU to 1420

on the outbounf Ethernet of the remotes and the Core router. The SQL would replicate after this.

The problem is we see very sporadic Replication of the Remote SQL Servers over the Satellite/VPN (GRE/IPSEC) tunnel.

The Servers eventually replicate after many tries.

We are trying to improve the reliability.

Citrix etc. has no issues over the VPN Tunnels.

Thanks,

Bob
