A method and apparatus for facilitating an activity switch between a
plurality of redundant routing modules in a network element is disclosed.
Lower layer protocol packets, each encapsulating a higher layer protocol
packet, are received at a lower layer task of a first routing module. The
method first determines a peer network element In response to failure of
a higher layer protocol task of the first routing module. The higher
layer and lower layer protocol sessions between a second routing module
and the peer network element are terminated following the determination
of the peer network element, wherein the second routing module functions
as a backup of the first routing module. The method then initiates a
switchover from the first routing module to the second routing module of
the network element.
