Configuring OSPF with ABR on SteelHead SD
– Hard reset - A hard reset tears down the connection between peers including the TCP
connection and deletes routes coming from the specified peer. Session will reestablish from the
start once hard reset is done. The prefixes in the BGP, IP, and Forwarding Information Base (FIB)
tables provided by the neighbor are lost. A hard reset is not recommended. Clearing a BGP
session using a hard reset invalidates the cache and results in a negative impact on the network
performance when the information in the cache becomes unavailable. A hard reset is also
disruptive because active BGP sessions are torn down.
– Soft inbound reset - A soft inbound reset is the same as soft reset but refreshes only the
inbound route table updates.
– Soft outbound reset - A soft outbound reset is the same as soft reset but refreshes only the
outbound route table updates.
4. Under Reset options, select:
– Selected BGP neighbor to reset the BGP session at the neighbor level.
– All BGP neighbors to reset the BGP session at a global level. Be advised that when you specify
this option, the BGP tab disappears as it is applicable to all BGP neighbors.
5. Click the search selector to select the BGP neighbor for which you want to reset the session.
6. Click Submit .
