[c-nsp] ACL sometimes logging dest_IP sometimes nexthop - why?

[Hank Nussbacher]

I have a config like this:


interface GigabitEthernet0/0/0/43.1
  ipv4 address 192.0.2.20 255.255.255.0
  encapsulation dot1q 1
  ipv4 access-group log-traffic ingress
  ipv4 access-group log-traffic egress
!
ipv4 access-list log-traffic
  10 permit ipv4 any any log


In the log I see:

RP/0/RSP0/CPU0:2024 Jun 19 05:12:47 : ipv4_acl_mgr[343]: 
%ACL-IPV4_ACL-6-IPACCESSLOGP : access-list log-traffic (10) permit udp 
192.114.102.104(55638) -> 192.0.2.2(53), 1 packet
RP/0/RSP0/CPU0:2024 Jun 19 07:59:19 : ipv4_acl_mgr[343]: 
%ACL-IPV4_ACL-6-IPACCESSLOGP : access-list log-traffic (10) permit udp 
128.139.197.54(16738) -> 2.15.248.225(33443), 1 packet


Sometimes, the dest_IP recorded is nexthop (1st line - 192.0.2.2) and 
sometimes dest_IP is recorded with the true dest_IP (2nd line - 
2.15.248.225).  How can I force the ACL to only record the true dest_IP 
and not nexthop?


The routing entry for all show like this:


RP/0/RSP0/CPU0:GP1#sho route 2.15.248.225
