Description (partial)

When removing 'router eigrp' and 'network' under router bgp at the same,  the following traceback may be seen,

   0x2b18f85 : __be_ip_route_update 
% 0xb90cc4 : __be_bgp_ipv4_rib_install 
% 0xb8fdb4 : __be_bgp_ipv4_rib_update 
% 0xb8bc81 : __be_bgp_route_update_fwdtable_walker 
% 0x9396b93 : __be_rn_walktree_version_locking 
% 0xb8bd98 : __be_bgp_update_fwdtable 
% 0xae5246 : __be_bgp_router_generate_updates 
% 0xadd330 : __be_bgp_router

This problem only likely occurs when 'router eigrp' and 'network' commands are removed at same time by copy-and-paste onto router console.  Under normal condition, if removing those two commands  one by one manually,  the issue very unlikely occurs.
