Re: astonishing problem of ping between CRS and GSR

It doesn't really matter that it's GSR/CRS in this case - GSR/GSR works without a problem just like 7200/7200. Are you running XR?

debug icmp

debug ipv4 packet ACL

where acl has permit 192.168.1.0/24

Re: astonishing problem of ping between CRS and GSR

Hi Cheng,

Cisco CRS series routers (like GSR routers running IOX ) act slightly different than other routers. Cisco IOX has a built in mechanism called Local Packet Transport Services (LPTS). LPTS is made of various different components , but in your case , you seem to be concerned with LPTS policers that rate limit the icmp traffic handled by the router.
