Congratulations on the achievement.
You already have experience working in one of the domains (Network), it would be good to focus on gaining experience on other domains so that it helps you in becoming a CISSP. You can pic a domain which is close to your area of work and interest (DR/BCP, Security Operations).
It would be prudent if you look at explore Software Development Security domain, as most of the applications are web based and there is a huge demand for people with good skills.
