Thank you Daniel.
It is true. It is version, platform specific.
R1 the RP is a 7200:
Rack1R1(config)#do sh ver | i IOS
Cisco IOS Software, 7200 Software (C7200-K91P-M), Version 12.2(25)S14,
RELEASE SOFTWARE (fc2)
Rack1R1(config)#
R5 is a 3600:
Rack1R5(config)#do sh ver | i IOS
Cisco IOS Software, 3600 Software (C3640-JS-M), Version 12.4(17),
RELEASE SOFTWARE (fc1)
Rack1R5(config)#
either for RP or BSR commands we have to enable pim on the loopback interface:
Rack1R5(config)# ip pim rp-candidate l0
Warning: PIMv2 not configured on Loopback0, Candidate-RP not advertised
Rack1R5(config)#ip pim bsr-candidate lo0
Warning: PIMv2 not configured on Loopback0, BSR messages not originated
Rack1R5(config)#
anyway. It is clear for me. To be on the safe side just enable pim
sparse on the RP and BSR :D .
Thank you for your support.
