Is their any known issue to configure the route leaking on the stub router. [Dual-homed hub-and-spoke WAN network]
I am looking for some eigrp stub leak-map configuration examples / documentation to better understand the technology, but it's seems I am not having much luck on cisco.com.

Hello Rasesh,
the leak-map option is associated with the
ip summary-address eigrp xx command
and allows to advertise some subnet components in addition to the summary route
see
http://www.cisco.com/en/US/docs/ios/iproute/command/reference/irp_eig1.html#wp1013188
There is no leak-map option associated to the eigrp stub command
The summary keyword permits the EIGRP Stub Routing feature to send summary routes. Summary routes can be created manually with the summary address command or automatically at a major network border router with the auto-summary command enabled. This option is enabled by default.
So you could use the summary-address command out the eigrp stub router but why?
if the summary route is enough it is better to advertise only that.
Hope to help
Giuseppe

Hi Giuseppe,
Their is a leak-map option assocaited to the eigrp stub command. You will find this option in version 12.3(11)T or 12.4
WAN_Router(config-router)#eigrp stub ?
connected Do advertise connected routes
leak-map Allow dynamic prefixes based on the leak-map
receive-only Set IP-EIGRP as receive only neighbor
redistributed Do advertise redistributed routes
static Do advertise static routes
summary Do advertise summary routes

Hello Rasesh,
I see and I think here the leak-map can have a different meaning:
for the prefixes specified with the leak-map the router can behave as a standard EIGRP router (for example it can learn and propagate prefixes matching the leak-map).
However, if it is so in a dual homed scenario the leak-map can increase the scope of the Query range involving the stub but leaking router.
Hope to help
Giuseppe
