The state of tBgpInstanceAlwaysCompMEDStrict specifies whether to compare Multi-Exit Discriminator (MED) path attribute between routes learned from the same neighboring autonomous system (neighbor-AS) in the route selection process. When the state of tBgpInstanceAlwaysCompMEDStrict is set to 'true' it specifies that the MED value should be only compared between routes learned from same autonomous systems and if one of the route has no MED it should be assigned the lowest possible value of 'zero'. When the value of tBgpInstanceAlwaysCompareMED is 'infinity' and the state of tBgpInstanceAlwaysCompMEDStrict is set to 'true', the MED attribute of two routes is compared if they come from the same neighbor-AS and the routes are compared as though the route with the missing MED has a MED of infinity (the worst possible value, 2^32 -1.).
