Inter Vlan or routing with L3 HP Flexnetwork 5130?

Question

Computer networks

Good day, dear sensei!
Your help is necessary if it is possible for "dummies" in a question vlanovoy routing.
I watched a lot of videos of Tsiska and Dlink, looked through forums, articles in which everything seems just from the command line, but of course this does not apply to the HP web interface and my crooked little hands.
In general, the L3 FlexNetwork Router from HP was installed at the enterprise, and so on. I'm the only one who knows the words IP address, network and switch - appointed senior to launch it. The former admin is now offline.
The situation is as follows, at the enterprise up to L3 in a single subnet there were Switches (about 50 pieces), V / cameras (for 200 pieces) and Computers (20 pieces) and, surprisingly, the range of free addresses is rapidly decreasing, and there are still a lot of v / cameras and recorders. That's actually the question arose about the implementation of L3 and stuffing everything into different Vlans.
The real situation is much worse than the one presented here, but as they say, Moscow was not built right away, I would like to understand the principle.
A simplified plan is as follows:
FlexNetwork L3
switch Allied Telesis
Host 1
Host 2

switch Created vlan 10.20 in Switches according to the scheme
In flex vlan registered IP addresses


I tried to ping the opposite gateways from the hosts and the ping went! from *10.211 to *.88.1 and vice versa from *.88.2 to *.10.211. I was so happy. for the first time in my experience, instead of a "general failure", a ping went between different subnets, even virtual

ones. Then I assumed that it was left to register static routes and it's



done. But the harsh realities landed a fledgling chick on the ground - nothing worked.
I tried different address options in "destination ip" and "next hop" and still nothing.
Help me to understand
