gateway api on gke got error "Size of the url map exceeds the maximum permitted size"

[pochingliu131]

Hello everyone.

Recently I started migrating my services from istio to gateway api on my multiple cluster gke. Because I have 100+ HTTPRoute need to create. When I already declared 30+ HTTPRoute I encounter some error "Size of the url map exceeds the maximum permitted size" It seems like that I hit "Size of URL maps" limit on my gcp(only 64KB for external LB) but it can't be increased or changed on myself. I understand it's all gcp's fault not gateway api. But maybe someone can help me on here?

Hey @totoroliu0131, do you mind filing a bug through GCP support so we can follow up there with all your project information?

yeap, I already sent request form to GCP, I understood that is not gateway api problem, just curious am I the only one experiencing this problem?
