Hi,
I recently configured AnyConnect on ASA 5510, 5512 and 5505 with split-tunneling and it's working great. You can refer to the configuration below:
webvpn
enable outside
no anyconnect-essentials
anyconnect image disk0:/anyconnect-win-3.1.14018-k9.pkg 1 regex "Windows NT"
anyconnect image disk0:/anyconnect-macosx-i386-3.1.14018-k9.pkg 2 regex "Intel Mac OS X"
anyconnect enable
tunnel-group-list enable
cache
disable
error-recovery disable
ssl-server-check warn-on-failure
group-alias sslgroup_users enable
group-policy clientgroup internal
group-policy clientgroup attributes
vpn-tunnel-protocol ssl-client
split-tunnel-policy tunnelspecified
split-tunnel-network-list value SPLIt-ACL
tunnel-group sslgroup type remote-access
tunnel-group sslgroup general-attributes
address-pool vpnpool
default-group-policy clientgroup
tunnel-group sslgroup webvpn-attributes
nat (inside,outside) source static 10.100.20.0-24 10.100.20.0-24 destination static 10.100.21.0-24 10.100.21.0-24
access-list SPLIt-ACL standard permit 10.100.20.0 255.255.255.0
access-list SPLIt-ACL standard permit 10.100.21.0 255.255.255.0
Question: I have multiple L2L VPNs configured on these ASAs. What I want to do is to access the resorces of those of L2L tunnels via Anyconnect. Is this do-able?
Thank you,
Abhi

I don't see why not. Once the packet gets decrypted and inside Firewall, it could go anywhere, including to another VPN tunnel.
What can prevent this from happen is routing, ACL and NAT.
You can run a packet tracer and simulate that, then, you can see which one from the above is preventing packets to get to the destination.

Thank you for the quick reply but I would really appreciate if you could just guide me through this. Webvpn is pretty new to me and I do not wanna mess the production FW.

Just run the packet tracer. It does not change anything and will give you a good grasp on where packets stops.

As mentioned, this is possible. What you need:
In a regular setup this is all what you need.
