Hi,
I have got an issue where SPOKE1 and SPOKE 2 cannot communicate with each other. However, SPOKE1 and SPOKE 2 can communicate with HUB. Please see configuration below for spoke and hub. I'll really appreciate if anyone could please guide me in right direction.

SPOKE 1 (Cisco SRST881, v. 12.4)

SPOKE 2 (Cisco 887VA, v.12.4(22r)

HUB (ASA5525, v.8.6(1)2)
