we are currently running a Cisco 7507MX with 2 RSP-16 Modules and IOS 12.2(25)S6. We are using SSO as redundancy mechanism. As 12.2(25)S6 is deferred we would need to upgrade.
our partner recommends the latest 12.3GD Release, but double-checking with the feature navigator, i can't find the SSO Feature in 12.3 Main.
is that true, that there aren't such redundancy mechanism like sso or rpr+ implemented in 12.3Main?
if so, it would be better to stay in the 12.2S Train, (e.g 12.2(25)S15) right?
i would be thankful for your comments,
