1. A method of operating a first network node in a communications network, the method comprising:
determining a number of operational links in a first link bundle including a failed link;
comparing the number of operational links in the first link bundle to a first limited operation mode number of links to determine whether the number of operational links exceeds said first limited operation mode number of links, said first limited operation mode number of links being a non-zero number;
making a first link bundle metric advertising decision based on said determination of whether the number of operational links exceeds said first limited operation mode number of links;
wherein said first link bundle metric advertising decision is a decision to advertise a normal link bundle metric for the first link bundle when the number of operational links in the first link bundle exceeds the first limited operation mode number of links; and
wherein first link bundle metric advertising decision is a decision to i) advertise a limited operation mode link bundle metric for the first link bundle or ii) refrain from advertising a link bundle metric for the first link bundle when the number of operational links in the first link bundle is determined not to exceed the first limited operation mode number of links.
