Hi everyone. I have a couple of easy questions about multilink via a 2650 router.
1. Should I set the snmp-server trap-source for Multilink1 or should it be on some other interface?
2. Should I set the logginf source interface for Multilink1 or should it be some other interface?
3. If I apply an access list that denys certain stuff (say tcp 135) to the Multilink Interface, will I have to rebuild the interface? Or can I just do a conf t then int multi, apply the access list, then write it?
4. If I want to do rate limiting, would I apply it to the multilink1 or some other interface? Would it blow away my multilink config when I implement this?
Here is my relevant config and probably some that is meaningless (sorry just want to be thorough):

aaa authentication fail-message

hi
AFAIK if u r NMS is placed in the same local lan where u r router lies then its bettter to to have source as ur rotuer ethernet interface.
its recomended to have either ethernet or loopback as source.
syslog message contains the IP address of the interface it uses to leave the router,so if ur syslog server is in local lan better use ethernet as the source.
theres no need to rebuild the configuration u can apply the ACL straight away without worrying about anything but do remember u r ACLs are cofnigured properly.
And again applyin CAR wont do any harm to ur Multilink interface.
Multilink interface is a simple logical interface built over the physical interfaces which has its own advantages as well limitaions.
