Cluster ASA ARP Refresh for floating IP of IBM SVC
SVC node 1 has IP: MGMTIP
SVC node 1 has MAC: MAC1
SVC node 2 (passive) has IP: MGMTIP
SVC node 2 (passive) has MAC: MAC2
MGMTIP is of MGMTVLAN
When node 1 goes faulty, MGMTIP floats to SVC node 2 (making node 2 active for management). It requires change of MAC address against MGMTIP. Other servers in MGMTVLAN can reach MGMTIP on node 2 MAC2. But ASA ARP entry still shows MAC1 for MGMTIP. When arp is cleared manually of MGMTIP, ASA immediately learns the new MAC2 and MGMTIP (on node 2) becomes reachable in the network. Manually ARP refresh is not practical. Need your support. Similar problem is noticed in FWSM as well.
Below is some output from ASA-5585-X:
arp timeout 14400

Hi, I want to redistribute OMP routes to BGP, i have the doubt if all of the OMP prefixes located in the local vEdge will be redistributed to BGP or just the connected+static networks located in the vEdge. Also how can i restrict some OMP prefix...
Let's say we have two routers configured as RP candidates for auto-RP: R1 - "advertising" its loopback0 interface IP address 220.127.116.11 as the RP for these groups:18.104.22.168/3222.214.171.124/32126.96.36.199/24188.8.131.52/16 R2 - "advertising" its loopback0 int...
