I have the scenario [Please seed the attached word doc],
Company B migrating with Company A
As part of migration, Layer two port channels were built between the companies, I spanned management vlan across the port channel from company B to company A, so that I can manage/make changes remotely to core A. After the port channels are built and vlan is spanned, The management vlan went to alt block on Company-B core for port channel 20; I can ping the management Vlan interfaces from Core B to Core A and vice versa.
The problem is I cannot telnet , Also when gave tracert from remote PC it crosses ISP hop and drops after core B; I don’t think I need to make any routing changes on the cores as at this stage I am treating core A as layer 2 switch getting through porchannels[though core A is running eigrp to ISPA]
I understand the both switches are not in same domain and not running same STP
Actions take: Disabled DTP[switchport no negotiate] on both portchannels, even then I am not able to telnet
Any ideas, suggestions
