Hi All members,
I want discuss one issue with all of you.
I am facing some issue on cisco 2811 routers. I am using very simple connectivity of ospf between core ,customer 1 and customer2 routers. I have disabled cdp on core router but customer routers A & B can see each other via cdp as show cdp neighbor. On cisco core router how we can disable multicast traffic or disable cdp so customer routers can't see each other via cdp.we do not have any control on customer routers. we have control on our router and access points. I know one thing, we don't have much options on our Access points but there is some way on cisco core router to block cdp traffic, i want to know how its is possible on cisco core router. is there any option?
On two different AP's on point to multipoint (pmp) scenario like this:
(Customer A Router1)---->Customer radio(Station)--------->AP1------>Tough switch-------->AP2--------->Customer radio(station)------->(customer B Router 1 ).
Equipment i am using:
Routers: 2811 cisco router
Customer radio: Ubiquiti Nano station M5
AP1 & AP2: Ubiquiti Nano station M5
And toughswitch of ubiquiti is connected to core router like multipoint customer of AP's scenario. Both Customers are different companies, they should not see each other router, may be they can ping or not.my question is this " how to disable cdp on core router or both AP's or customer radios, we don’t want that both customer can see each other router, we want they can ping but can’t see other. If i do show cdp neighbor on each customer router, i can see other router. although client isolation in enable on both AP1 and AP2, multicasting and extra reporting are disable on radios. We do not have any control on customer routers or devices, like we can’t disable cdp on customer routers in real and live situation. I have also tried to disable cdp on core router but customer routers can still see each other.
our main concern are:
1)both customer routers should not see each other via cdp, but they should pass traffic.
or
2)both customer routers should not see each other, also should not ping each other.
I have checked with by disable the cdp on core router but customer can still each other (A & B routers).
is there anything we can do on AP's or customer radio or cisco routers to resolve above two issues.My main concern is now Is there any thing we can do on cisco core router, to disable cdp traffic that customers can not see each other.
All suggestions and solutions are requested to solve this issue.
Thanks & Regards,
